Port forwarding with airport & external router

Hi,
I'm happy with port forwarding normally, but I've just made my network entirely wireless and can't figure out the answer to this problem. I have a non wired netgear router as my internet access point, an airport express is connected to this getting its address via DHCP, another airport is joined to this network, and 2 macs are connected to the airports again getting addresses via DHCP. How do I port forward to the macs using this setup? I can't figure it out. Obviously I'll need to configure manually, but if I open the port on my router and open the same port on the AX will they go throught to the mac ok. Do I map the router to forward to the AX manual IP then map the AX to a specific mac IP? Any tips appreciated before I go ahead and break my network
Emma

Emma,
Ok, here are my thoughts. Have you tried assigning static IPs via DHCP, not manual config, based on client MAC addresses? Meaning when the router sees an ethernet MAC address it always assigns the same IP to that machine. This should enable the handing out of IPs while retaining port forwarding to the same machine each time and still preserve the routing that DHCP seems to enable more betterer . I'm not familiar with the netgear setup and I couldn't get my AX performing satisfactorily for my needs either so I have returned it however this is a 'somewhat' common option when setting up DHCP on different routers and I have found it works better when daisy chaining through routers.
HTH,

Port Forwarding with Airport Express 802.11n Utility version 6.1

Hi all,
Quick question, hoping it can be solved with a quick answer
Not sure what I'm doing wrong: I'd like to set up port forwarding for Skype and Transmission, however in the airport utility even when I assign the public/private ports to the ones specified in the respective programs (with the IP address for the machine I am using), if I go into Transmission or onto a port checker website the connections are shown as closed for the ports I have selected (on the public side).
I've made a DHCP reservation for this machine to tie it to a given IP address, and I've enabled NAT port forwarding protocol in the Network options (no default host so far).
Also, in case it makes a big difference, right now I'm connecting to the internet via a Cisco DCP3825 cable modem running in bridge mode, with the AEBS in DHCP and NAT router modes.
Any tips?
Thanks!

Sadly I never got it to work. I called up Apple and they claimed that all the ports are open for the Airport Express, but if I run port scanner in Network Utilities none of the ports I specify show up as open unless I select one of the "Default" port categories like "Windows File Sharing". I told this to the person I spoke to on the phone, and they replied several times in a row that they are not allowed to help set up port forwarding, that they can only provide info on how to open the ports, and that even if the ports are subsequently not opened or forwarded they can't provide any assistance. It wasn't a very good conversation. Unfortunately, based on some of the other disucssions I've looked at in this forum, it doesn't seem possible to do conventional custom port forwarding using this version of the Airport Utility. Hopefully someone will correct me though. Sorry I can't be more help.

How to port forward with AirPort Extreme

I really just cant find an accurate description in the support community. Err, let me rephrase: I'm not tech-savvy enough to really comprehend all aspects of port forwarding within the AirPort utility.
I am trying to set up a server for a game (Starbound) and I have been trying for hours to open 1 port. I believe it connects through TCP on port 20125.
I cant seem to figure out which IP address the utility needs. The router's? Which IP address is the router's if so? How do I see that?
I wish server was freeware so badly, I've watched videos and tried to replicate the results manually but I just absolutely can't get it. Would really appreciate support on this, as I've never encountered this problem configuring port forwarding in a browser-based scenario.
Thanks all. All I really need is a walkthrough to open that ONE port.

For reference the following AirPort User Tip will give you the basics for port forwarding.
I cant seem to figure out which IP address the utility needs.
What is required is the IP address of the host device that you want reached from the Internet. In this case it would be the server hosting the Starbound game.
It is highly recommended that you configure your server with a static Private IP address. You can do this using the DHCP Reservation feature of the AirPort Utility. What this does is assign a dedicated address from the pool of addresses that are provided to local network clients. You will then use this address to populate the IP Address field for the port mapping. Note: Port Forwarding and Port Mapping are used interchangeably. Apple uses Port Mapping.
To assign a DHCP Reservation:
Start the AirPort Utility, select the AirPort Extreme, and then, select Edit.
Select the Network tab.
Click on the "+" button under the DHCP Reservations window.
For "Description," enter Starbound or whatever you want to describe this port mapping.
Reserve Address By: MAC Address
MAC Address: (Note: This will be the hardware MAC address of the server's Ethernet or wireless interface.)
IPv4 Address: [enter the desired IP Address that you want to assign the server. It should be from the available pool of DHCP addresses. By default this pool is: 10.0.1.2 thru 10.0.1.200. For example, you can use 10.0.1.100
Select Save
Using the reference provided earlier, use the AirPort Utility to define the port mapping that you require. (Note: You should still be on the Network tab.) I filled in the values for you. Note, however; that you may need to change the value for the IP Address field to the address that you set earlier in the DHCP Reservation.

How to port forward with Modem and Router

I have a Linksys AM300 Modem and a Linksys WRT610N router.
I want to forward ports for Call of Duty Modern Warfare 2 and STEAM.
How do I port forward when I have 2 devices and how can I test that it is working?

I would recommend that you reconfigure your AM300 into bridge mode. In bridge mode it operates like a standard modem would do. Then reconfigure the WRT610N for your internet connection, i.e. most likely PPPoE. Now the WRT has a direct connection into the internet. Now you only need to configure port forwarding on the WRT610N.

Port Forwarding with Port Translation RV042, RV016, RV082

This is a feature request for the Linksys RV series Routers. Currently, it appears that the Cisco/Linksys RV042, RV082, and RV016 only support port forwarding and 1-to-1 Nat. One item that I find very helpful with customers is port forwarding with port translation. I am requesting that this feature be included with a future firmware relase for these RV series routers.
Here is an example of the request.
Take an incoming service request on a TCP or UDP destination port and forward it to an internal IP on a different TCP or UDP port. For example, customer A wants to allow different machines on the internal network to receive Windows RDP connections inbound. To make PC maintenance identical between the internal machines, the customer does not want to change the listening port for RDP on the individual PC workstations through the Windows Registry. The customer also does not want to dedicate separate IP's to each machine in a 1-to-1 NAT setup. The only option is to have remote connections to each of these PC's to use a different destination port. So, for example, PC one could be reached on TCP port 5151, PC two on TCP port 5152, and PC three on port 5153. This requres a firewall that is able to translate each of these connection requests to a different internal IP on the default RDP port (TCP 3389). So, the following setup is required:
Port Forwarding with Port Translation:
Router External IP on TCP port 5151 ---> forwarded to PC One's internal IP on TCP 3389
Router External IP on TCP port 5152 ---> forwarded to PC Two's internal IP on TCP 3389
Router External IP on TCP port 5153 ---> forwarded to PC Three's internal IP on TCP 3389
There are several comparable "small business" class router competitors to the RV042, RV082, and RV016 that will perform this port forwarding with port translation process without incident. Unfortunately, these Cisco/Linksys small business routers will not accomplish this task currently.
Please implement this feature in a future firmware release.
Thanks!

Excellent. I see this now. None of our customers actually use the UPNP feature, so we never realized that Port Forwarding with Port Translation features existed on this page along with the ability to enable or disable UPNP.
Perhaps, in the future, this functionality could be moved to and incorporated into the port forwarding page which seems to be a more logical location.
In either case I'm very happy to know that this feature is available on the RV's.
Thanks for your assistance.

Port Forwarding with Verizon-Branded Action GT704-WG

I am new to the forums, and I am already overjoyed with the 30 minutes I spent figuring out that the login mechanism does not even work with browsers other than IE7/8. Lots of fun to start.
I live in a residential building with the residential High Speed Internet Plan. I assume this is the case because it is a DSL line and they are not using business grade, or I do not think I would be having these problems.
I have spent many hours trying to figure out how to port forward with the above-mentioned router/modem/gateway/**bleep** extraordinnaire. I am in IT professionally, and I am tired of feeling **bleep**. I called Verizon tech, but they were very unhelpful unless I pay for a premium tech service to figure out port forwarding problems. And yes, I have read the info on port-forward.com numerous times for this device.
Essentially, I want to forward an arbitrary port, let's say 6336, to a server running Ubuntu 9.10. I have put this computer in the DMZ using the web interface. I have also set up a mapping rule to forward 6336 (all three entries pointed to 6336 in the Security/Applications/Forwarding section, following docs on port-forward.com for this specific model AND Verizon's own documentation). Occassionally, I can see the service is viewable from the likes of canyouseeme.org. Nonetheless, I cannot access the port: I get a connection refused error when using ssh on this port. Yes, I correctly configured ssh on the DMZ server/host to respond to the non-standard 6336 port, and I have tried it with the server's firewall system (ufw/iptables, for the curious) enabled and disabled. It NEVER works.
Some posts here have indicated I might need a static IP assignment. That can be done only client-side (meaning the Ubuntu server in the DMZ), if I understand people saying it is not possible to do static assignments from this **bleep** gateway, so I am not sure if that should matter (I wonder what happens with this **bleep** when two computers try to demand the same static IP; dare I guess that he asks first wins?). I cannot recall if I have uPnP enabled or disabled as I am at the office right now, but I believe it is off. Not sure if this matters either. If I am wrong, I would love if someone could let me know. I am at a loss and sick of dealing with such a simple problem. I would really appreciate the help.
Solved!
Go to Solution.

Ok.
#1 On your computer setup a Static IP.
This means following the directions at http://www.cyberciti.biz/tips/howto-ubuntu-linux-convert-dhcp-network-configuration-to-static-ip-con...
#2 The Static IP must be outside of that DHCP range of the router. So, this means your IP has be above 1 but below 64.
#3 In the router forward to the IP Address that you setup on the computer.
OR if the router can give the computer the same IP Address each time, you could do that.

Port forwarding with E2000 for a game called Minecraft.

Okay, I've been wanting to port forward this game called Minecraft for quite awhile now, but never got around to it, but now that I've wanted to let my friends that can't play with hamachi play with me. I wanted to port forward it so that they go into the game without using hamachi, or any other networking program. If anyone knows how to acomplish this with a guide for this then it would be nice, or just simply write out instructions. I've already tried once and whenever I ran my server, I would say "FAILED TO BIND TO PORT" or just ask me this "Is another _____ running on that port?" Thanks for helping guys,

Yea it looked okay. Go to cmd, then type in ipconfig. Look for your ipv4 address. Now make sure that address is the same as the one that you set up port forwarding for in your router.
Make sure you have reserved that ip by going to 192.168.1.1--->Basic Setup--->DHCP Reservation---> (your PC). Now restart your PC. The important thing is to make sure that your local ip matches everything (Port forward, server.properties, and the DHCP Reservation Table)
Now go to the .bat files that you downloaded for the minecraft server. You should see a file called "server.properties". Go into it and make sure that the server ip matches your local ip (192.168.1.4 for example). If not, change it. Here's a reference video: http://www.youtube.com/watch?v=6MJVNxPtmtM

Configuring the time capsule airport wlan function as "connect to wlan", the time caspule gets a correct IP adress from the other wlans IP range, but does not assign this to the ethernet ports. With Airport Express it worked!

Configuring the time capsule airport wlan function as "connect to wlan", the time capsule gets a correct IP adress from the other wlans IP range, but does not assign this to the ethernet ports. With Airport express it worked, the single Ethernet port got the IP Parameters passed through!
My setup is a Vodafon Esaybox connected to ISP. Time Capsule is not able to extend the wlan of the easybox, neither airport express can do.
Only the option "connect to wlan" is succesful.
With airport express I was able to connect my Sony Bravia TV to the lan via ethernet to stream pictures, the TV set got an IP adress from the easybox.
With the time capsule the easybox dosn't find devices connected to the ethernet ports to submit IP adresses. The TV set get another IP adress (169.xxx.x.x.) in subnet mask 255.255.0.0 and I don not now where from.
My notebook is a MacBook pro.
Any idea????
Thank a lot in advance!
Kind regards

Neverthe less, could there be the chance, that this feature could be implemnented with an firmware update?
That would appear to be a question for Apple to answer. You can make suggestions to Apple here:
Apple - AirPort Extreme - Feedback
If the AirPort Extreme and Time Capsule are configured to "extend a wireless network" they will provide additional wireless coverage....and...the Ethernet ports are enabled in this type of setup.
The "catch" here is that you must have an Apple router providing the network to be extended.

Port forwarding for airport utility 5.6.1

Hi,
The previous version of airport utility had a simple tab "port mapping" that allowed me to forward ports so that various servers running on my machine could be accessible via outside of my WAN/LAN. However, when using the latest version, I don't see anything related to port mapping, the closest I found was an IPv6 Firewall-- which I am not certain is what I am looking for......
Ultimately, I have a development web server that I run on port 3000, and I want this to be accessible from the outside world--- and also I would like VNC guests to be able to do screen sharing / remote access which I believe is through port 5900... How can I make these two things accessible through my standard IPv4 address?
Thank you.

Tesserax, you seem to be the Airport Extreme guru. Been trying to find answers on forums all day so as not to duplicate a post. Also tried to find a way to contact you directly so as not to get off topic here...but couldn't see an option.
Running Airport Extreme Version 7.6.1. Hosting a FileMaker Pro 10 file on a PowerPC on my home network (ISP is TimeWarner ...ugh). Need to publish this file to the URL the gent that hosts my site has pointed at my public IP addy here on my home network.
Created DHCP Reservation by MAC Address for the machine hosting to achieve static IP. Have opened ports 80 and 5003 (filemaker) in Port Mapping. Both pointing at the IP addy of that same machine hosting the file. Some discussions have said to make the end of IP .201 or higher for port forwarding so I've done so.
Port checkers all say these ports are still closed. Time Warner has told me they are not blocking either of these ports and that my modem does not have a firewall holding things up—they say the prob is with my router settings.
I should probably also mention that I used to successfully forward these ports and host/access this file via the URL (same ISP and domain host etc. then as currently).
Obviously posting here because none of this is working. Have looked over the links and docs you regularly reply with—hoping you may have other wisdom to give us. Thanks in advance.

Port forwarding with natd

I have set up my Leopard Server with a public ip on Ethernet, 85.165.220.114, and a private ip on the Airport interface, 192.168.207.200.
This is working well, I can access my server with a registered domain name from the internet, with web, ssh etc.
Now I want to forward port 12000 to a device on my network with ip 192.168.207.245, and put this into /etc/nat/natd.plist:
<key>redirect_port</key>
<array>
<dict>
<key>proto</key>
<string>tcp</string>
<key>targetIP</key>
<string>192.168.207.245</string>
<key>aliasIP</key>
<string>85.165.220.214</string>
<key>aliasPortRange</key>
<string>12000</string>
<key>targetPortRange</key>
<string>12000</string>
</dict>
</array>
I have Firewall setup and running, and NAT running on my server.
Port 12000 is checked in Firewall, and that should be it.
Port forwarding should now work, but it doesn't.
Looking at Firewall log, it looks like the Firewall is doing it correctly:
Aug 10 11:02:46 leopard ipfw[66524]: 12315 Accept TCP 84.212.229.188:57224 192.168.207.245:12000 in via en0
Aug 10 11:02:46 leopard ipfw[66524]: 12301 Accept TCP 84.212.229.188:57224 192.168.207.245:12000 out via en1
So I am completely lost why this does not work as it should.
Ivan

I got it working at last. I removed the Airport, and made a second Ethernet interface in system preferences - Network. The second interface populated with the private IP address, and gateway with the same private ip (192.168.207.200).

Ospf forwarding address for external routes

I read this in a document:
"When OSPF learns an external LSA, it makes sure that the forwarding address is known
through an OSPF intra-area or interarea route before it installs it into the routing table. If the
forwarding address is not known through an intra-area or interarea route, OSPF will not install
the route in the routing table."
I am trying to understand from where this requirement comes from? Why OSPF will not install the route in the routing table if the forwarding address is known via ospf external route?

Hi,
the originating router sets the FA to a non-zero IP-address only when certain conditions are met:
The interface pointing to the next-hop IP of the external route
has to be OSPF-enabled (non-passive)
AND
has to be a multiacces-interface (network type broadcast or non-broadcast)
So if there is no OSPF interal route to reach the FA on other routers, someting went wrong and it's safer not to install the route.

How to Port Forward on Cisco 1900 Router?

We have a cisco 1900 router. I m new to cisco routers commands, recently started learning. I need to forward all requests coming from port 1723 from outside to inside server ip. I check "show running-config" and I see already forwarded ports and ip like below,
ip nat pool onlyone xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx netmask 255.255.255.252
ip nat inside source list 1 pool onlyone overload
ip nat inside source static tcp 192.168.0.xx 22 xxx.xxx.xxx.xxx 22 extendable
ip nat inside source static tcp 192.168.0.xx 80 xxx.xxx.xxx.xxx 80 extendable
ip nat inside source static tcp 192.168.0.xx 80 xxx.xxx.xxx.xxx 96 extendable
ip nat inside source static tcp 192.168.0.xx 443 xxx.xxx.xxx.xxx 443 extendable
ip route 0.0.0.0 0.0.0.0 xxx.xxx.xxx.xxx
where xxx.xxx.xxx.xxx is public facing IP.
so what is the command to add "ip nat inside source static tcp 192.168.1.xx 1723 <public-ip> 1723 extendable" to currnetly working settings?
I am currently reading below but no luck so far...

How do I know if "interface ethernet 0" and "interface serial 0" will work for me?

the router is already setup and working for 2 years. all i need to do add a simple port forward from public ip to internal server. Following make sense to accomplish what i m trying to do. Lets assume 1.2.3.4 is my office public static ip and 192.168.0.10 is my internal server. All requests will come from some Ip lets say 25.24.23.22:1723 to 1.2.3.4:1723 and router will forward this request to 192.168.0.10:1723. This is all i m trying to accomplish. I m not setting up a new router. Some rules are already there. Therefore below seem to be what i need. All I need is how to identify "interface ethernet 0" & "interface serial 0". I understand the inside and outside details. All i have to find is how to replace ethernet 0 and serial 0 with what i have in my router setup.

Single Port Forwarding on a WRV210 router

I was wondering if anyone can tell me how to forward a single port to a different port to a specific computer for the WRV210 router?
I would like to forward port 10100 to port 25 to my mail server. There are times when our people are at a hotel and they block port 25 and I have done this in the past on a BEFSR11 and BEFSR41 router. There does not seem to be a Single Port Forwarding setup page and the Port Forwarding setup page only allows you to forward a range to a specific computer, it does not give you a different port you can assign an incoming port to.
I have the most current firmware revision, 2.0.0.11, and Hardware Version WRTR-221G_V01.
I look forward to any replies.
Fred.

Will it ever be able to support this? seems like a pretty reasonable request since this device is billed as a small business device.
so far i have spent over 1000 dollars on cisco gear first 2 rvs4000 to do BO vpn
then 2 wet200 thinking i would be able to create a bridge to my garage while wireless users could surf. little did i know that the wet200 could not be an AP.
i then went looking for a cisco small business AP only. could find one at any local retailer. so i bought the wrv210 and removed my rvs4000 seems i just downgraded myself. i should have just gone out and bought a $40 dlink AP.
very disappointed. hopefully you can share my experience with someone who can explain why a small business device wouldnt want to use port redirection.
If you see a bunch of used cisco small business gear online thats me,

Single port forwarding with a E2000.

I was wanting to port forward a port that was 25565 for a game of mine, but everytime I try it won't work. someone give me a walk through?
By the way, it's 7AM and I didn't sleep yet so i'll explain more detailed in the morning.
I'm using a E2000 Router.

Best thing would be to set a dhcp reservation for your pc/notebook and then set the port at the single port forwarding page to your int. IP.
