WRT54G v2 with Strict NAT when connected via ethernet to Xbox 360

Hello, I apologize if this is in the wrong board as the router, although it is a wireless model, is connected to the Xbox 360 via ethernet cable, so I was a bit torn on where to place it. Router Model, Firmware version: WRT54G v2, v4.21.1 The problem and details are as follows: The Xbox 360 is running on the default settings. Literally, I plugged it into the router via ethernet and it automatically grabbed an IP (192.168.1.101) and the right information to connect to Xbox Live. The router is still running the default range of 50 IPs, so 100 to 149; the 360 was just the second thing to connect. Another computer is connected to the router via ethernet and a laptop is connected wirelessly, if this might affect the case at all. When using the Network Test feature of the Xbox 360, everything is operating perfectly except the NAT is giving me a Strict reading. Some of my games require an Open NAT for me to be able to access some features such as hosting a co-op match. Simply put, what do I need to do inside the router's settings that would give me an Open NAT on the Xbox 360?

well try reducing the MTU values to 1365 on the router, also try triggering 88, 3074 ports on the router...

Apple TV (1G) doesn't appear in devices list when connected via ethernet

After upgrading to OS X Lion and iTunes 10.4 my Apple TV (1G) doesn't appear in the devices list when connected via ethernet. When I switch to wireless lan the device is shown and the sync process starts but can't copy the new films. The copy operation stops every time and sometines the device disappears from the list.
Despite of the upgrading of OS X and iTunes all the settings are unchanged.
Anyone an idea?

Since my last update, I've gathered more information. I'm almost certain this is not entirely a 10.7.1 issue, if an issue in 10.7.1 at all. 10.7.1 may have changed something that caused this issue to appear,but where I was having this problem weekly if not daily, I no longer have the problem. I changed routers. I was using a new D-Link Xtreme N Gigabit RouterDIR-655. This router was causing me pain with lock ups. I replaced it with a Cisco Linksys E4200. I have not had a lockup in over 2 months now and not one sync issue with Apple TV nor my new iPhones, which sync wireless to iTunes on my Mac Pro.
Thinking about how my network is wired leads me to believe the issue was in the router, or maybe a network communication change in 10.7.1 that the DIR-655 was not supporting correctly. My MacPro and a few other hardwired access points in my house go directly to the router. My AppleTV and Airport Extreme are connected to a Gigabit switch and the Gigabit switch is then connected to the router. I also turn off the wireless capabilities in my routers, as I prefer to let my Airport Extreme handle those duties. This all means my normal hardwired communication path from my Mac Pro to Apple TV was going through the router, to the switch, to the Airport Extreme and then to my AppleTV. My Apple TV is connected to the LAN port on the Airport extreme. By going wireless on the MacPro, I was bypassing the router altogether.
As I started out saying, since I replaced my router, my sync issues have also gone away. If your having Apple TV sync issues, you might want to look at the router as well. Also, while I can’t remember the exact settings, I had opened up or enabled UPnP and other router settings in the DIR-655 to see if that would resolve the sync issues and it did not. In the end, I just spent the money and bought a new router and life is good now.

I have a Airport network at home with a Time capsule connected via ethernet cable to modem. Also the network is extended wirelessley with an Airport Extreme. I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme. Can my network operate properly to extend the network with both a wireless and wired extend functionallity?

Excellent plan.
Can my network operate properly to extend the network with both a wireless and wired extend functionallity?
Yes, but don't get confused about the second AirPort Extreme, as it would not be configured to "extend" a wireless network.....it would be configured to "create a wireless network" using the same wireless network name, security settings and password as the Time Capsule network. Configure the second Extreme in Bridge Mode.
This Apple support document will show you how to hookup and configure the second AirPort Extreme:

APE only works when connected via ethernet

I have a new AirPort Extreme that I am trying to add to my existing network (an older APE base station and 2 Express) and no matter how I try to configure it, I can't get it to work without being connected with an ethernet cable (either to my MacBook Pro or to the other APE base station).
I also tried setting it up on its own with a new network and that wouldn't work either.
If it isn't plugged in, and I try to change the configuration, i get this error:
"AIRPORT UTILITY WAS UNABLE TO FIND YOUR BASE STATION AFTER RESTARTING.
The settings for this base station have been successfully updated, but there was a problem re-joining the wireless network or finding the base station. You may need to select your network from the AirPort menu and try again."
The amber light flashes, and it never shows up again. It doesn't matter if i unplug the APE, turn AirPort off and on, restart the utility, restart my mac... it won't ever show up unless I connect via ethernet, but as soon as i connect the ethernet cable, everything works fine.
Does this mean that there is something wrong with the APE, or is there something I'm doing wrong with my setup (I've tried the assisted setup and manual setup following the instructions in the "Designing Air Port Extreme 802.11n Networks" pdf)?

Yes. It's just the one APE that is a problem. The rest of the network is fine.
If I connect the new APE to the older APE with an ethernet cable, I can see it in AirPort utility and use AirPort Disks connected to it, too; but as soon as I unplug the ethernet cable, it can't get back on to the network and it no longer shows up in AirPort utility.

Problem with AppleWorks documents when connecting via ftp to my server

When I connect over the internet using ftp to my mac mini server (using OS X server 10.4.10) from my iMac G4 (using 10.4.10) all my AppleWork docs will only appear as .bin instead of .cwk.
If I download one to my G4, it will try to open using stuffit expander but cannot be opened. It comes up with “An error ocurred attempting to expand name.bin unspecified Stuffit Engine internal error” Error #17999
However Microsoft Word docs show correctly and can be downloaded and opened without problem.
When I try directly on the server or try from any computer on the local network conected to the server, everthing views correctly and can be opened.
Could it be to do with any settings on the server when connecting by ftp.
Thanks for the help.

One problem still remains that when I download minicad files (which uses OS 9) they show up as .exe and will not open or recognisable by the programme
I imagine the file is transferring without a suffix and your computer is trying to guess what it is; hence the .exe. Delete this and append the suffix for the correct program and it should open (or use File>Open within the program).

Solaris 10 issue with the DNS when connected via DHCP

driver alias for Realtek RTL 8029 AS - ni0, driver is installed from http://homepage2.nifty.com/mrym3/taiyodo/eng/. IP, shown on ADSL modem TP-Link ADSL2+ Router TD-8810 - 192.168.1.1 .
To connect to the Internet in the terminal I enter:
ifconfig -a
ifconfig ni0 unplumb
ifconfig ni0 plumb
ifconfig ni0 192.168.1.5 netmask 255.255.255.0 up
route add default 192.168.1.1
After that, I can turn on ADSL modem or the computer hangs)
Now in the terminal I enter:
ifconfig ni0 dhcp
The computer connects to the Internet.
Problem: does not work DNS, visible are only addresses without a domain name (eg http://86.106.213.1:8080/).
ping 89.33.1.18 - is alive, ping boom.md - the domain for 89.33.1.18 - host unknown.
I tried to:
cp /etc/nsswitch.dns /etc/nsswitch.conf
and
write DNS-server in /etc/resolv.conf in format:
nameserver <IP-address>
After running DHCP nsswitch.conf file is back to default, not using DNS, a resolv.conf file after a reboot does not exist. Domain names are still unknown.

I'm using exact scan already and have switchresx.
I've actually solved the problem, don't ask me how.
I connected it up via the VGA interface to see whether that would make a difference, the picture was centralised but the resolution was not great.
So I swapped it back to the HDMI interface, rebooted the Mac and when it came back up the HDMI 1920x1080 desktop was perfectly aligned.
So have no idea why but it is now working.

My new computer with Windows 8.1 does not recognize my iPhone when connected via USB.

My new Dell Computer with Windows 8.1 does not recognize my iPhone 5 when connected via USB. I have reinstalled iTunes to no avail.

Hey, I may have to if I can't get this one to work!!
I have tried a different USB to no avail. Both cables work on my old Dell so I don't believe they are the issue.
I uninstalled iTunes as directed by Apple Support and reinstalled. Apparently, Apple Mobile Device Support is not loading with it because it does not show up in programs.

The iTune Remote App has stopped finding my iTunes library when connected to wifi from my main router, but works fine when connected via second wifi router on the same network (different SSID)

I'm running iTunes Remote App from a couple of iPhone 5's and a first generation iPod Touch. iTunes is running on a PC - Windows 7. My home network runs two Wifi Routers, each with a different SSID. I've had no problems with the Remote app running this set up for the last 8 months but recently the App can only find my iTunes library when the iPhone/iPod is connected via one specific router, when connected to the network via the other router, no iTunes library is found. I'm also running an Apple TV and it's the same as the iTunes Library, only visible via the one SSID.
Everything else seems to work fine when connected via either router, eg Internet on the iPhones (definitely via wifi)
I've tried renewing the lease on the iPhone wifi connection, restarting everything.....several times.....
It used to work fine, this only seems to have been a problem in recent weeks
Any help or advice would be much appreciated
Thanks
Ian

It turned out to be the firewall settings on our router. Her machine was sending traffic that our router interpreted as a DoS attack and blacklisted her Airport's MAC address. That's why it would work fine if she switched to Ethernet.

I have an HP LaserJet 8150N that I am trying to get connected via ethernet cable directly to my iMac. I always had this printer connected via a network so I don't know if I am able to connect directly with a cable since it is a network printer.

I have an HP LaserJet 8150N that I use for my work and I have had this printer for ever and it is one heck of a work horse! I am trying to get it connected via ethernet cable directly to my iMac. I always had this printer connected via a network so I don't know if I am able to connect directly with a cable since it is a network printer. I have tried to reconfigure the printer using the JetDirect menu giving it a new IP address but still no luck. If anyone could help me through this issue I would appreciate it.

Second, seeing "connecting" and connection failed is normal. You must click on "Connect As" in the Finder window and then enter the username and password for the admin account on the other computer. That should fix things.
Thanks for responding.
When does clicking on "Connect As" happen in the process above?
After step six? Seven?
After the connection has failed?
Is this the FInder window that shows the icon of the computer you want to copy the file from?
You should see "Connect As" in the Finder near the top right of the window as shown below:

T420 - external 24" monitor DVI- Displayport : not detected when connected via KVM switch

Hi,
I've been using a 2port USB KVM Switch from InLine for a long time connecting a mac mini and a macbook pro
to a 24" LCD. Recently I had to replace the MacBookPro with a T420. Unfortunately the T420 does not detect the
monitor, when connected via the KVM switch.
I tried:
A) T420 -> Lenovo Displayport to DVI-Adapter -> KVM-Switch -> 24" monitor: NO SUCCESS
B) T420 -> Thinkpad miniDock Series 3 DVI Port-> KVM Seitch -> 24" monitor : NO SUCCESS
C) T420 ->Thinkpad miniDock Series 3 DVI Port-> 24" monitor - > SUCCESS
D) T420 ->Thinkpad miniDock Series 3 VGA Port -> 24" monitor - > SUCCESS
So I have a workaround, but leaving out the KVM switch is not a long term option.
This is all on Win 7 professional / 64bit
Using config (A) I then installed the Intel HD Graphics Driver version 8.15.10.2342 16 May 2011
SURPRISE: during driver install, the monitor WAS detected!!!
SECOND SURPRISE: after reboot I was back in the old situation where the monitor was NOT DETECTED
CONCLUSION:
Seems like a software issue with the Intel HD Graphice driver.
ANY HINT/COMMENT/HELP highly appreciated!
Thanks,
Michael

hey mgold,
as the T420 works correctly with the external monitor and with the miniDock ; it is sad to say the the KVM switch is non-compatible.
I would recommend that you get in contact with the manufacturer of the KVM. At the same time, try uninstalling the current video drivers of your T420 and see if it makes any difference with the KVM if the T420 is running on a generic driver

10.6.1: Can't resolve FQDN when connecting via WLAN / Airport Base Station

Hi everybody,
after hours of work and having read many helpful topics in this forum (and other) I've successfully setup a Single Signon Environment for my home office. It's a dual core macmini server running 10.6.1 and only mac clients.
The server is connected via switch to my airport extreme base station. This airport station uses PPPoE to connect to my ISP and it has the DHCP service running, handing out the clients' IP addresses. The server and the switch have all static IP addresses.
My issue is the following:
Whenever I connect via wifi or vpn using my MBP, I am not able to "bind" to the server (via system preferences : users : login setting) using the FQDN. The error is "can't resolve address. -2200" Instead it only finds myserver.local - and then I am able to set up my wifi connected client.
However, when I set up the client with the .local address I am unable to get a kerberos ticket for my users. The ticket viewer says, that it can't resolve the address for myserver.mycompany.private
I was able to get afp or ical to work on my vpn or airport connected clients when I used the server's IP address instead of a domain name - but only with kerberos turned off and with other problems.
I've heard that if everything is configured right, the server should show up in every clients' sidebar with its FQDN and NOT the bonjour name. Right now it shows only the bonjour name - even on the clients connected via Ethernet.
The other strange thing is that when I log into my client system I still have to authenticate with ticket viewer in order to get my kerberos ticket. Usually Single Signon should work with the login window, right?
I really don't know what else to do. I double checked my DNS settings and everything seems ok. I entered the FQDN of the my server in the airport stations' DHCP settings as "LDAP server" - nothing changed...
Do I need to use the server's DHCP service instead of the airport station's DHCP? And if I do this, how to I turn off airport's DHCP? It does not seem to be possible when connected via PPPoE to my ISP.
I am unsure what to do in order to get things to work. Anybody out there who can help?

Hi Davidh and thanks for posting!
I had 3 DNS entries in my client's network settings - one was the server and the other 2 were from my ISP. Removing the ISP's DNS entries and keeping the server DNS IP solved my kerberos issue. Wow!
I'd never thought that it won't work with more than the server given as DNS entries. I'll need to check this with my iPhone later, because I had a similar issue with that device yesterday when trying to connect via VPN.
Thanks very much!
Still one question:
The sidebar of my clients still don't show the server's FQDN - but only its bonjour name. Is this right? I read in another forum that the client's sidebar should show the FQDN if everything is configured right.

OS X Lion gets kernel panic when connecting via CIFS

A customer of ours has problems with OS X Lion clients that get kernel panic when connecting via CIFS (Novell OES server).
Any new on this issue?

This is how the problem occurs:
1. Mount the CIFS share - no problems
2. Use the share - no problems
3. If the network connection drops you get a message that the CIFS volume has disappeared and you are asked to unmount it. When you do that you get a kernel panic. You can force the problem to happen by turning of WiFi.
So it is OES2 but which version (SP1, SP2, or SP3)? Interesting as I'd only heard of this with NetWare 6.5.
Do you (and anyone else experiencing this issue in this thread) know if this has recently started happening, perhaps after the latest November 2011 Scheduled Maintenance patches were installed?
I'll hopefully be able to do some testing tomorrow but in the meantime I've asked Novell ...
HTH.

I have a problem with using MacBook Pro as wifi router when connected to ethernet

I have a problem with using MacBook Pro as wifi router when connected to ethernet. The Airport icon changes to show a laptop inside, my iPad shows connected (I think) but Safari will not operate. I tried pinging my iPad, it seems to see the iPad, but no connection to Safari or to other apps such as Good on the iPad. I have read many posting and tried repeatedly via Sharing in Systems Preferences, but no luck. Suggestions to fix, or is this a Lion problem?

Usually this is a problem related to the domain name server address. If you open Network preferences, select your Ethernet port then click on the Advanced button then on the DNS tab. You will likely see an entry like 10.0.1.1 already listed. Click on the Add [-] button and enter 208.67.222.222 then click on the OK button and then on the Apply button. See if this helps.
if it does not help then repeat the above but with the Airport port.

Out of the blue, my ITouch is unable to access my wireless network ONLY when my PC has been turned on (PC is connected via Ethernet cable, and has no wireless capability as far as I know). What gives? It works fine when the PC is off.

Does the iOS device connect to other networks?
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
I suspect a problem with your router. Try changing the security. First use no security as a test.
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
