Filter Internet NAT Redirection

Hi i own a WRT150N router, and while playing xbox 360 I get the NAT needs to be set to moderate or something error. I'm am in my linksys menu online, but i can't find the option that says to switch to open NAT. The only thing I've found on NAT was Filter Internet NAT Redirection which was unchecked for me. I know there are a bunch of threads out there but I searched and couldn't find any that answered my question. Sorry if this is a repost, but any help would be greatly appreciated.

well...you need to go the "applications and gaming" tab and click on "port trigerring" subtab , trigger the ports 88 and 3074 .. let me know if this helps you to get rid of the error message ..

Buffer Overun and Filtering NAT redirection...

Sometimes I use my own computer as a server to host PC multiplayer (online) games. Every now and then I get a buffer overun message. Basically it happens after 3 hours of hosting a game server. Now, I was sure it was probably someone trying to do a DoS attack or hack my server, so I enabled NAT redirection filtering on my router as well as Block WAN requests. After, no more "Buffer Overun" messages appeared even if I host a game for more than 3 hours. When I would take off the NAT redirection filtering it would happen again.
My router is a WRT54GS v.6 and my ISP is COMCAST cable internet service. My router has the most recent updates from linksys, so I'm guessing it's a firewall issue with my router not blocking intruders from accessing local servers or other connected devices (my local network).

hi... try reducing the MTU to 1365 on the router and try enabling "NAT redirection filtering" on the router...

EA6500 NAT Redirection Bug???

I have a pair EA4500s that I am swapping out for a pair of EA6500s. One EA6500 is a router. The 2nd EA6500 is set as a bridge and us being used as an Access Point about 200ft and two floors above the main EA6500 router. The two units are connected via DECA (200MB Ethernet over DirecTV cable - an alternative for others with a cable provider is called MOCA). So, basically two EA6500s serving as two Access Points on opposite sides of the house and all wireless networks on different channels but all sharing the same SSID. Everything works GREAT except for one unusual issue.
The issue is with wired or wireless clients. If I try to use my PUBLIC address with port number to address a local client on the local network inside the NAT network the NAT redirection fails. In other words if I use 172.16.16.8 for a local web cam while inside my network from an iPhone or PC all works great. If I use the external public address, however, the connection times out. If I pop out the EA6500 doing the routing/NAt and swap it with the old EA4500 with basically the same config as the EA6500 everything works again. The EA6500 and the EA4500 are configured identical for the most part and with the EA4500 as the main router NAT redirection works great but with the EA6500 NAT redirection fails. I have the firewall setting to FILTER NAT REDIRECTION unchecked so that's not the problem.
Seems very odd.... and only seems to happen with the EA6500..... the work around is to use the local IP address when the client is on the inside and the public address when on the outside, but what a pain that is....
I think this must be a bug. Anyone else able to reproduce this issue... I have not reset the router EA6500 to factory and reconfigured from scratch. That is my last resort that I'm dragging my feet on.... but no idea if that will solve anything anyway... just an idea I've not tried yet...
Thoughts?

Thanks for the comment but unfortunatly I think you may be are responding some other post that has some issue with SSID or WiFi??? Might check that you are responding to the correct post given I'm not aware there was any comment or issue about wireless or SSID or even a 2.4ghs or 5ghz issue here. My issues are with wired clients but I cna alos reproduce the same issue over WiFi as well.
Unfortunatly, SSID and wireless functionality have nothing to do with this thread or the issue. This is a NAT REDIRECTION problem that happens on wired clients even if WiFi functionality (guest and regular) is disabled and the 2nd EA6500 is removed completly. This is a routing or firewall issue I suspect.
In regards to wireless (not a problem in this case), all works fine wiht the same SSID on 2.5Ghz and 5Ghz on two different WiFi devices. Thanks for the feedback and info but SSID is irrelevant and I regret now even mentioning it in the original post given it has no bearing on this issue. I was just trying to be complete in my description of the environment.

ADF Table Filter Internet Explorer 7 and Internet Explorer 8

Good afternoon,
Currently I am creating a table that has filters.
So I configured the component column: Filterable = true
It works perfectly in Chrome and Internet Explorer 9.
It does not work in IE7 and IE8. It allows you to enter the filter parameters, however nothing happens.
Anyone know how to solve?
I am using:
JDeveloper: 11.1.2.1.0
Integrated Weblogic: 10.3
Chrome: v16.0.912.77 m
IE 9: 9.0
IE 8: 0.4 IETester
IE 7: IETester 0.4 and IE7

Good morning, thanks for reply
Shay, the project that this problem is stopped for the next two weeks, so return, I will test and report
if it worked or not.
fetishcode, his suspicion was correct, IETester does not work perfectly in this case
Thank you all staff and developers Oracle ADF

JMF over the Internet / NAT problems

Hi folks,
I wonder if someone could help me out. I'm trying to get RTP streaming to work over the internet; specifically to get a server (with a public IP) to send an RTP stream to a client behind a NAT (so with a private IP address). This is the set-up I have at the moment:
Client expects RTP traffic from server to arrive at its local port A. The server sends out RTP traffic from its local port B (i.e. the RTPManager running on the server is initialised with port B).
Before any RTP transmission occurs, the client sends a few UDP packets from its local port A to the server's port B and also to a different port C. The server listens to these packets on port C, and extracts the client's public IP and port (i.e. the IP address of the NAT router plus the public port on the NAT that is mapped to port A on the client).
When the server starts the streaming shortly afterwards, it sends the RTP packets to the public IP/port it detected earlier. The idea being the NAT should forward those packets to port A on the client. But this doesn't seem to be working....
Does anyone have any ideas what's going wrong? Has anyone else had to tackle similar issues?
Thanks in advance for any help.

Some sites recently became blocked on my computer. I either get I'm not connected to the internet or redirected. How do I fix this?

I went on vacation, when I came back the following websites were blocked. Facebook, Cracked & TMZ. I cannot access them from this computer either with Fixfox or IE. They can be accessed by other computers at this work. Is there a way to unblock them?
With Facebook, I get the message saying I'm not signed onto the internet. With the other 2, I get redirected to Yahoo.com.
Anybody have any ideas?
Thanks

Cisco ASA VPN to Internet NAT

stevemoores wrote:
"interface" means just that, the IP address of the interface, so make an object with the x.x.x.100 address and try using that instead of interface.
That is what I am thinking and trying now.

Hi Everyone,
Running 8.4 on Cisco ASA. When a user is connected via VPN a subset of internet traffic is required to go outside via our office internet connection. I have that working fine but it is using the outside interface IP instead of a particular IP I want to use. Below is my NAT statement but I am not sure how to amend so it uses the address I want. I assume I need to replace interface with something that specifies the NAT I want to use?
Outside interface is x.x.x.99 and is what sites see when VPN traffic is routed out to internet.
I want the traffic to show as x.x.x.100

HT1338 iMac Internet sites redirecting

About a week ago audio advertisements have started playing in the background on my iMac. Also, when I click on a web site, I am frequently redirected to an unrelated and unwanted site! I started getting messages that my flashplayer needs updated, which I tried to do. When I click to update the flashplayer, a messsage of gibberish appears about the windows product I tried to install. My iMac is about a year old and uses OS X Version 10.7.5.

Too many redirects?

WRT610n access external ip from within LAN - NAT loopback

Hi everybody,
I've replaced my old ZyXEL P-320W with a WRT610n and lost one feature...
I basically have a NAS assigned to IP 192.168.1.2, my router has IP 192.168.1.1 locally of course.
Imagine I have IP X.X.X.X from the internet and that this IP is registered to myip.dyndns.org.
In the old days (with my ZyXEL), I could ssh to my NAS using myip.dyndns.org from within my LAN, but now, I HAVE TO use the local ip (192.168.1.2) to access to it...
I've done some research and found out that this feature is named "NAT loopback" and the closest to that feature I've found in the router configuration is "Filter Internet NAT Redirection" (in Security > Firewall) but enabling it or not does not make any difference...
Did you guys already experience this? Is there a solution?
Thanks in advance
Jon

Basically,to access the NAS...you have to use the local ip address...As far as the SSH is concerned,You need to open port 22 on the linksys router.Check this link.
For logins using ssh keys permissions are very important to make it work. By default in WRT root's home directory is "/tmp". Create a directory called "/root" and changed root's home directory to this (edit the /etc/passwd file). Put your DSA and/or RSA keys in "/root/.ssh/authorized_keys" and "chmod -R go= /root" on the WRT. It should work...

"Loopback" or "reverse NAT" on EA2700 / DB N600

I'm having some trouble finding the right setting on the included tools - I'm familiar with how to do it in ddwrt but don't want to change from stock on this one.
What I have is that I want to be able to access certain ports via my public IP address (Instead of local network address) from within my house. For example, internal address is 192.168.1.125 to point to a given device, and I have it mapped out on the public IP address - (fake IP) 129.252.67.60:8080 to point to that device. I can access that public IP address fine from outside of my home network, but if I try to do so while connected to my home network, it will not connect. (Of course, I can connect to 192.168.1.125 fine from my home network.)
From what I recall and have read, I need to turn on "loopback" or "reverse NAT" somehow to let the router know to point the external IP address request right back...
If anyone has any advice/fixes, I would greatly appreciate it - I have settings on my computer/tablet that I would prefer to not have to keep two separate versions of (One for external networks, one for internal networks) if it can be avoided.
Thanks in advance,

Ensure the box "Filter Internet NAT redirection" IS CHECKED on the security tab. Selecting the checkbox and saving worked for me to get Loopback within my network

The mother of all iChat AV problems

All the computers listed below can text chat among themselves but almost all of them cannot audio or video iChat AV with each other.
I hope you can follow along, as this will get very complicated. It is a hard story to tell.
I have been working on this for about 3 weeks now. I have read just about every post in the past 3 weeks. A 2nd Level Apple Tech Support person said I should post this for all to read because it encompasses so many problems all at once without any results and I have some interesting situations. I have tried every single suggestion in the forum without any results. I have spent hours on the phone with Apple iChat support, 2nd level Apple support and Linksys support. I’m an experienced iChat AV person and have been video conferencing for 10 years, starting back with CU-SeeMe. Actually did Beta testing for that CODEC. At the end of this, I will tell you what I haven’t tried yet, and it’s only one thing. And Ralph Jones of the UK, I have read every page of your website about ichat AV and tried everything on it. Thanks for the good work along with everyone else.
I’m the tech administrator for a Day Care Center. At the Day Care Center there are 15 Macs; 12 new 14 inch iBooks - 1.3 GHz with 756 MB RAM, one -15inch PowerBook 1 GHZ with 1 Gig RAM., an iMac 1 GHz with 1 Gig RAM, and one – 17inch 1.67 GHz PowerBook with 1 Gig of RAM.
My office has 2 Macs using iChat AV, a PowerBook 400 Titanium – 500 MB RAM and a G5 – Dual 2GHz – 3500 MB RAM.
All ADSL connections, all Verizon DSL. There are 8 different locations involved in this. 7 locations are using Linksys WRT54G routers, version 2 and 5’s, all updated to the latest firmware. My office is using a Linksys WRT54GS version 1 also updated to the latest firmware. 7 locations are using Westell 2200 DSL modems, and the one residential location that is DHCP is using a Westell 6100 Modem, the 6100 is set to default settings.
7 locations have static IP’s from the ISP and the 8th location is DHCP direct from Verizon (a typical residential set-up). Each location has 2 computers associated with it, all with iSight cameras. All 17 computers are using iChat AV through an AIM account.
All the computers are running OS 10.4.3 and are up to date as of this posting, including the J2SE 5.0 ver. 3 update and the Security Update 2005-009.
At my office and the office of the Day Care Center, all the computers are designated with a static IP. At the other locations the computers are DHCP, set to automatically get an IP from the router.
In all attempts to video iChat with all the computers, whenever an attempt is made, the 2 computers always get a video preview window and they say, “Starting video chat with …”, but then the dreaded responses always follow after trying to accept; “Did not respond”, “Fail to start video chat”, or “Cancelled the connection.”
So first, my office and the Day Care Office (DCO) have been video conferencing for over 1 year with iChat AV, but now we can no longer video chat. The only thing that changed was at both locations the routers went form an older Linksys WAP54G (A, B, & G) router to the WRT54GS ver. 1 at my office and a WRT54G ver.2 at the DCO a while ago. I can no longer video conference to the DCO nor can they video conference to me between any combination of the 4 computers at the 2 locations (a G5, PB 400, PB 1 GHz, iMac 1 GHz.). Not to long ago they all could video iChat with each other.
My office (with both computers) can iChat with the one location that is DHCP (the Verizon residential setup – both routers set to their defaults, no special stuff). But I can only video conference with the iBook not the PowerBook. In reverse, the iBook can call me but the PB can not. I have brought the PowerBook back to my office and it can video iChat back to the iBook at it’s location from the PowerBook that came from that location. The PB can even connect to my 2 computers on my router at my office. We did a 3 way to the iBook with my G5 hosting, the PowerBook at my office and the iBook at it’s location. When I take the PoweBook back to it’s original location (where the iBook is – the residential location) it can’t video conference with my office, no matter who calls whom.
In the remaining 6 locations, none of the computers can iChat with any of the other locations at all. I have only been able to iChat with the one location that is the Verizon DHCP location (residential setup) and only to the iBook not the PowerBook.
Now to get even weirder, as I said each location has at least 2 computers. At each of the 7 locations (but not my office), the 2 computers at that location, on the same router, can iChat between themselves over AIM (not BonJour) but they can not video chat with any of the other 7 locations.
All 17 computers connect correctly to the Apple iChat test sites: appleU3test01 and appleU3test03 at very good speeds. Oh speaking of speeds, when I first thought maybe it was a connection speed problem, I checked each location by downloading a file off the ISP’s server to check actual speeds, no connection is slower than 75 KB/s, most are plus 150 KB/s downloading the file. I tried 5 different DSL speed websites such as DSLReports.com and they are so inaccurate for testing speeds, they’re not worth using. I would get variations of speeds sometimes 400 to 500 Kbps difference between web services from the same computer at basically the same time.
To recap, my office G5 can only chat with one computer of the 17, the iBook at the Verizon residential setup. The PowerBook from the residential setup can chat back to its home connection to the iBook from my office only. None of the other computers can chat with each other from one location to the other. All the computers (except my G5 and the one iBook) can only chat with the other computer that is located on the same router.
I have concentrated on trying to get my office and the DCO connected. I have tried everything. That’s why after talking with Apple about this, the tech said to post this. Not many people will have so many computers simultaneously to work with. He even said I tried everything.
The one thing I haven’t tried is removing the Linksys router from both ends of a connection and just go through the Westell Modem. There is too much involved changing over the 2 offices or the other locations with all the computers at each location. I can’t afford to experiment that way with working business situations. These are not home environments.
I’m still not sure if the problem is an Apple thing with the latest updates or a router problem because the firmware updates have installed a lot of security stuff. I never had to even consider Port Forwarding or anything. iChat AV with the Linksys routers in their default settings just worked.
One odd thing I noticed while I did all this testing, if you have 2 computers at the same location that both have the same apple test site in the buddy list (example: appleU3test01) when one connects to the test site, the other computer lists the buddy as in use, and the second computer can not connect to it. As soon as the first computer disconnects, it becomes available to the second computer. You would think the test site can handle multiple people at the same time. In addition, each computer can connect to a different test site at the same time over the same router. I don’t know what it means, I just found it interesting.
Thanks for listening,
Jim

EZ Jim & Ralph, I appreciate your suggestions.
EZ - I have not had time to view entirely your website on ichat. It looks pretty complete. Too busy. Equipment conflicts I don't believe I have any. There is nothing on any of the computers except the iSight camera. No other external or internal equipment added. Very little software other than Microsoft Office 2004 and a cople of other things. They are not loaded with stuff, pretty basic.
Also each little network location works fine, the only thing I'm having trouble with is Video Chat. They all text chat to each other just fine, including the Windows machines (some locations have windows xp machines only).
Ralph - first - each Day Care location is in a different building around our community and each has a DSL line with it's own static IP from the internet service provider. Each location has one Westell Modem/Router 2200 that has been made into a modem, setting it up as a bridge as my service provider requested. And each location has a Linsys Router with the Static IP to the ISP. Each computer has it's own AIM address.
On the Modem I changed the IP address so it wasn't the same as the Linksys Router.
I want to say, I think like you that it's the modem. I got that feeling from your last post.
I have checked out my G5 and I can Video Chat to a lot of people (settings below). I restored it back to the way it was originally set up when I could video chat with the Day Care Center Office (DCCO). I can chat with my son (he has similar Linksys WRT54G Router, the version I still don't have, and an iSight camera), my parents (they have a cable modem, and an old Linksys A&G Router, iSight), my neighbor (I lent him one of my iSights, he has Verizon Fiber Optic and a Apple Extreme Base Station). All video chatted fine.
My Linksys is now set to defaults. I restored everything back. This is how it was prior to all the testing (port forwarding, etc.)
Security: Firewall protection is enabled. Block Anonymous Internet Requests, Filter Multicast, Filter IDENT (Port 113) are all checked and on. Filter Internet NAT redirection is not checked.
Administration: UPnP is Enabled.
Applications & Gaming: No Port Forwarding, No Port Triggering, No DMZ, No QoS.
The one thing different in all this is the Modem. I am using a discontinued Westel Wirespeed model; A90-210015-04.
My son is using the same type Router (different version) but a different Westell modem (I don't know which yet) He has Version DSL. The Router is set to defaults like mine is now and we conference fine.
The DCCO who I use to video chat with but can not now, has had the Modem and the Router changed. They had an old Linksys A&G router and an old discontinued Westel Wirespeed model similar to mine (the model I don't know yet). Now they have a Linksys WRT54G ver. 2 and a Westell 2200 Modem/Router (set up as a modem only).
So I'm going to work on the Modem theory first at the DCCO. I'm going to try to put the old modem back and see if it works. I can only do this on Fridays when only one person is in the office. I can't shut them down to test this. So I'll get back to you after Friday.
Thanks again for your good and helpful suggestions.
Jim
Gee, I wish they would have left the spell checker in this forum.

Remote Desktop Connection with WRT54G from Novice

Well, I’m usually pretty good at using Google and forums to eventually figure out how to fix my problem but this one absolutely has me stumped and I’m hoping someone out there has an answer for me. For the record, I have probably a beginner/intermediate knowledge of computers so if you know the answer to my problem, try to explain it simply! ****TO ANYONE WHO TAKES THE TIME TO READ THIS THING AND CAN OFFER SOME ADVICE-THANK YOU!!!!***
THE PROBLEM
I would like to be able to use Remote Desktop to log into either of my home computers from basically any computer on the internet.
THE SETUP
I have two computers, whose names are LAPTOP and DESKTOP that are both running Windows Vista Ultimate. Both of the computers are connected to a Linksys WRt54G Router ; one wired, the other wirelessly. The Linksys router is then connected to a Westell DSL Modem that connects to AT&T’s internet service.
SETTINGS
My DSL service only provides me with a dynamic IP address so I signed up with no-ip.com. Through that site, I bought a domain name and downloaded their small program that runs in the background of my desktop computer. The program checks what my IP address is every couple of seconds and if it changes, it notifies their server so that anyone who types in my domain name is directed to the new IP address.
ROUTER (Firmware 4.20.6)
Basic Setup Page: The Router Name is just the model number, the Server Name is my DSL provider and the Domain Name is the name I chose and registered with No-IP.com. (www.mydomainname.com, for example.) DHCP Server is ENABLED. DDNS Service is DISABLED. Under Advanced Routing, it is set in GATEWAY mode.
Security Page: Firewall Protection is ENABLED. Block Anonymous Internet Requests is NOT checked. Filter Multicast, Filter Internet NAT Redirection and Filter IDENT ARE checked.
Applications and Gaming Page: I chose two port numbers, one for each computer that I want to connect to. On the first line, I have Application: RDP, Port Range: 49200 to 49200, Protocol: Both, IP Address (The IP address of the computer I want to connect to) and the Enable box IS checked. [I did the same thing with the second line for the other computer, but with a different port number and that computer’s IP address)
Administration Page: Access Server is HTTP, Wireless Access Web is ENABLED, Remote Management is ENABLED through Port 8080, and UPnP is ENABLED.
WINDOWS VISTA SETTINGS
First, I went to the Remote Desktop Settings of the target computer and ENABLED Remote Desktop Connection and allowed computers running any version of Windows. I also confirmed that the box labeled “Allow This Computer To Be Controlled Remotely” WAS checked. I then made sure that I had a user name, it had a password associated and that it had Administrator priveledges. I went back to the Remote Connections screen and added the user name as being allowed to connect. (I think this is redundant since it’s both the owner of the computer and has Administrator Status.)
Next, per Randomly Googled Internet Advice, I went into the registry and changed the port number that Remote Desktop listens for incoming connections to Port 49200 to match the router settings. [Registry Entry that I modified was: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp]
Finally, I went to the Windows Firewall and Added (opened) port 49200 for use as a Remote Connection. I kept the protocol as TCP and confirmed the scope was set for Any Computer.
CURRENT STATUS
If I go to Explorer and enter my IP address with a colon and the specify port 8080, I can get the login screen for the router. Same thing happens if I just enter my domain name and port 8080. However, if I switch the 8080 port and use one of the ports I chose (49200), it cannot connect, either using the Public IP address or the domain name. (I’m trying to connect using a wireless card and not connected to my local network so I know it’s the same as if I was anywhere else.)
I’m not sure why it won’t let me connect; it feels like the router will not allow the connection to pass through it to the port I’m asking it to forward to. I’m guessing someone out there who took the time to read it is shaking their head at all the information I provided and knows the one dumb thing I missed!
Thanks again!

I'm attempting to do the same thing with my home network. the only differences are that i have cable internet from comcast and i'm running vista business. my router is the wrt54gs. i'm assuming that the web page is similar for adjustmants. To be honest i cannot figure out how to do a remote destop too. so i went to www.logmein.com and installed the program. once installed to to every computer you want to have access too and log into the website. then click on the add computer icom. full control app sharing etc... even better when you connect you have the option to deactivate the local host mouse and screen to prevent anyone seeing what your doing.
If you resolve the router issue would you let me know. plz thanks

PS3 / Xbox 360 / PC Router Guide For GAMERS

Downloadable for Wordpad or Microsoft Word: http://www.filefactory.com/file/b1e67ga/n/Gaming_Router_Guide.rtf
Or just read below:
PS3, XBOX 360, PC GAMING
Router Guide and Modem Guide
Introduction:
Having issues trying to get your PS3, or XBOX 360 from Strict, or Moderate NAT? Want to get Type 2, "Open" status? Then follow this guide step for step.
(Please refer to your manual or other posts if you are unsure how to access a certain step, or post a quick reply on the forum. You can usually access your Linksys router via Internet Explorer by typing 192.168.1.1 - password is usually admin, username blank or admin as well.)
All of these steps were performed on the following test setup:
1 - Laptop PC (Windows XP)
1 - PS3 Console
1 - Motorola Cable Modem (SB6120)
1 - Linksys Router (WRT310N V1)
Firmware Update:
1)   Download the latest firmware for your router
2)   Install firmware onto router.
3)   Wait 1 minute after it has finished
4)   Unplug your Cable or DSL Modem's power, and ALL other devices that connect to the router. Leave them off.
5)   Click the "Reset to factory defaults" button in the router."
6)   Wait 1 minute after the lights stop flashing erratically.
7)   Physically go to the router, using a pointed object press the "Reset" button and HOLD for 30 seconds, then release.
8)   Access the router interface (example: 192.168.1.1)
Quick Tips and Information:
*The following settings are assuming you are now at "Default" settings. If you are not, than some settings may have been overlooked and you may have the wrong settings.
*You MUST use a WIRED connection for these steps. You can even use your PS3 or Xbox 360, and use the browser to access the router if your console is a wired connection. That is what I had to do, because my laptop is wireless only.
*The biggest mistake people make, is not clicking "Save Settings" at the bottom of each page, before moving to the next section. You MUST click "Save Settings" on each little page. Including the sub-pages. This is a huge deal. Even though the settings will "Stay" how you clicked them, they do not actually go into effect unless you hit "Save Settings" on every page.
*At this stage, any unnecessary devices must be turned off. Only the router and one device should be connected through wired Ethernet. Use that device to perform the following steps:
SETUP > Basic Setup
9)   Internet Connection Type: Automatic DHCP
10) MTU: Manual, 1500
11) DHCP Server: Enabled
12) Start IP Address: 192.168.1.2
13) Maximum Number of Users: 2 (set for how many devices you have. 1 laptop, 1 ps3 = 2)
14) Client Lease Time: 0
15) Time Zone: Set for your time, and "Check" automatically adjust for daylight savings.
*Click “Save Settings” before moving to another tab.
16) DDNS and Mac Address Cloning tabs should have "Disabled" option set.
*Click “Save Settings” before moving to another tab.
WIRELESS > Basic Wireless Settings
17) Change to "Manual"
18) Network Mode: Wireless-G Only (My laptop is wireless and has a G-card. Set accordingly)
19) SSID: set this to something you like: (example Pro Gamer)
20) Standard Channel: 11
21) SSID Broadcast: Disabled
22) Wireless Security and Mac Filter tabs should have "Disabled" option set.
      *Click “Save Settings” before moving to another tab.
WIRELESS > Advanced Wireless Settings
23) AP Isolation: Disabled
24) Frame Burst: Enabled
25) Basic Rate: All
26) Transmission Rate: 54 Mbps (I am using wireless G. Set accordingly, but do not use auto.)
27) CTS Protection Mode: Disabled
      *Click “Save Settings” before moving to another tab.
SECURITY > Firewall
28) SPI Firewall Protection: Disabled
29) "Uncheck" ALL options: Filter Anonymous Internet Requests, Filter Multicast, Filter Internet NAT Redirection, Filter          IDENT, Proxy, Java, Active X, Cookies.
      *Click “Save Settings” before moving to another tab.
30) VPN Pass-through tab: should have everything "Enabled"
      *Click “Save Settings” before moving to another tab.
APPLICATION AND GAMING > All Tabs
31) Skip this section for now, however if you did NOT reset your router to defaults before beginning. UNDO anything you         already have enabled on each of the five tabs.
ADMINISTRATION > Management
32) Router Password: change to something you use
33) Web Utility Access via Wireless: Disabled
34) Remote Management: Disabled
35) UPnP: Disabled. Including the 2 options below it.
      *Click “Save Settings” before moving to another tab
36) On the Diagnostics tab, click "Reboot" (may be located on very first page under “Setup”)
37) Restart whatever machine you are currently using to do this.
38) Turn on all devices that will be connecting to the router, except the cable/dsl modem.
39) Log into the router with your new password. On the first, page you should see "DHCP Reservation" click this. At the top, you should see one device named PS3-something probably numbers. If it is blank but there is an IP address, that is okay too. Click the box to the right side of it. Your other devices should be there too, such as laptops and consoles, etc. Click the box next to each of them. Then Click, "Add Clients" Now you have just assigned a Static IP Address without going through the hassle of doing it manually. Now you will always have the same IP Address for each device.
      *Click “Save Settings” before moving to another tab
40) Go to "Application and Gaming" click on the "DMZ" tab. Change DMZ to "Enabled."
Source IP Address: "ANY"
41) Now for the most important part. Most people use destination IP Address. However, if for some reason your IP address of your device changes, well then you are screwed. So instead, click MAC Address, then click "DHCP Client Table" and then "Select" the device that you GAME on, such as PS3 or Xbox360. Click "Close."
      *Click “Save Settings” before moving to another tab
***** IF you game on multiple devices, such as a desktop computer, and a ps3. You must DISABLE DMZ, and instead ENABLE UPnP. Please be sure to also enable the 2 options right Below UPnP. Many people do not enable the third, and sometimes even the second option. This causes hosting/joining issues, as the ports do not open/close properly. If you only have 1 gaming device, DMZ is the better choice. However, if you game on more than 1 device, use UPnP.
***** DO NOT ENABLE DMZ & UPnP TOGETHER.
42) Go to "Administration" > "Diagnostics" > "Reboot"
43) Restart ALL devices (Except cable/dsl modem) then connect them to the router.
44) I would connect my laptop now, by using the dell wireless manager I have, use the wizard to find "Non-Broadcasting"       devices. Then I manually type in my SSID: (Pro Gamer) it pops up. Click "Connect,” then "Lock" then "Apply"
45) For my PS3 I turn it on, go to Network Settings, then Connection Settings, "CUSTOM"
      Leave everything Automatic or "Default" except for these:
      MTU: 1500 / UPnP: Disabled (If DMZ is enabled on the router) / UPnP: Enabled (If UPnP is enabled on the router)
If your console (ps3/xbox360) was the wireless device, then simply select, "Wireless" and click manual SSID type "Pro Gamer" or whatever your SSID is, then continue with the rest of the settings. Security should be none/disabled.
ALMOST DONE!
This next tip is almost completely UNKNOWN by the gaming community. However, it is spectacular. Did you know the cable companies increase their speeds over time for FREE? Here is how to get your free upgrade. Even if your speed does not change, this will upgrade your Cable Modem's firmware! (DSL modems must be done manually, check online.)
Use a 7/16 wrench if connections are too tight.
While the Modem is OFF, unscrew the coax cable from the modem. PAY ATTENTION to this step. Now unscrew the other side from the wall or splitter. Then, REVERSE them. Reconnect the coax cable to your modem using the OTHER side (the one that was plugged into the wall), and vice versa. Make sure they are snug, but do not over tighten.
What does this do? Well I do not know the exact inner workings, but my friend who works for Comcast told me about this trick. It forces their system to re-register your Cable Modem. So now, you get a new IP Address, and it forces your modem to check for the latest firmware update. Along with that, come your increased speeds for FREE.
a)   Now, plug in the power to your modem. Wait until all lights are steady.
b)   Then go to your computer, (Do not use the PS3 or Xbox for this step)
c)   Type 192.168.100.1 (might be different for your modem, Google it)
d)   This is your MODEM's page.
e)   Look around for an option that says, "Reset to Defaults"
f)   Click "Reset to Defaults"
g)   Wait 30 seconds. It will not do anything.
h)   Now, you must click the other option, "Restart Cable Modem"
It will now clear out the memory, check for new firmware, get an updated IP address, and hopefully give you improved speeds!
That is all. Happy gaming! Visit www.speedtest.net and www.pingtest.net to test your connections.

Hey thanks for this, but one thing I have to ask is about the modem part. I unhook the cables and reversed them and then turned on the modem the lights are on and stable now. I have a sb6121 and when the modem is completely active it goes green, blue, blue, green, which is power, downstream, upstream and then online. But when I did what you said it is green, blue, "green"!, green. So since its different do I wait for the upstream to turn back to blue, or do I have to call comcast and give them the mac address again? I have been waiting for 5 mins so far and don't want to restore defaults and restart till I know I should for sure.

Aaack. Adding a PC to my Happy Mac Family, adding a router?

Okay, I have 3 Macs connected to a DSL modem via Airport Express, WEP encrypted network. Two Macs run 10.4.8, one runs 10.2.8, all have Airport cards.
Hubby's new job comes with an IBM Thinkpad running latest version of Windows. New Co. insists he uses "their" router, and sent us a Linksys WRT54G. They say adding this to our network is easy, just plug it in. Huh?
Any advice or suggestions would be most welcome.....
Elizabeth

The Linksys WRT54G is a wireless router and performs basically the same functions that that AirPort Express Base Station (AX) does, except for sharing a USB printer or streaming iTunes.
You won't need to use both routers, but if you do, you would need to re-setup the AX as a "bridge." Your network configuration with both routers, would be something like the following:
DSL modem > (Ethernet cable) > [Internet port] Linksys [LAN port] > (Ethernet cable) > [Ethernet port] AX
If you elect just to use the Linksys, then just remove the AX from the above network configuration. The Linksys router comes with Windows-based setup software, but it administration is also web-based...so you could your Mac to set it up by way of Safari.
The following is a typical Linksys router setup for DSL:
Linksys Router Setup - DSL
- Access the Linksys web-based setup at 192.168.1.1 (or whatever address your router is set at) using a web browser. The default username is blank & password is "admin."
Setup tab
- LAN IP Address: 192.168.1.1
- Subnet Mask: 255.255.255.0
- WAN Connection Type: PPPoE
-- User Name: <ISP Account Name>
-- Password: <ISP Account Password>
-- Service Name: (optional)
-- Connect on Demand: Max Idle Time 5 Min. (enabled)
- Apply (if you make changes)
Status tab
- WAN (all the values here should be populated by your ISP)
DHCP tab
- DHCP Server: Enable
- Starting IP Address: 192.168.1.n, where n should be greater than 1
- Number of DHCP Users: n, where n should reflect the realistic number of concurrent clients that you plan on having connected to the router at any given time.
- Client Lease Time: 0
- DNS 1, 2, 3: <leave at default>
- WINS: <leave at default>
- Apply (if you make changes)

WRT330N firewall blocks AXIS 206W webcam traffic

I upgraded my Linksys WRT54GS to the WRT330N and so far, so good. The WRT330N is really a significant improvement.
However, I can't get my AXIS 206W webcam to work. The webcam is registered on the Axis website and creates it's own IP address. So when I try to enter the webcam over the internet, I see in my router's logfile that it blocks the request for that particular IP address. Disabling my router's firewall solves the issue but that is obviously not desirable. I never had this problem with my previous Linksys router's firewall.
Any thoughts?

Sorry for the delay, here it is:
Product and software version: AXIS 206W Network Camera version 4.40 External IP address: 68.193.237.187
It seems that if I disable Filter Internet NAT Redirection the camera works. Is that a security concern?
