HELP -- Two IP addresses when attempting network games.

[robpay]

I have cable hookup with a linksys 4-port router to share the connection.
The network works great -- sharing files, internet, printer, etc.
I was attempting to network at Jane's Combat.net with WWII fighters.
It doesn't work because somehow the center is giving me 2 IP's. The suggested fix is to check to see that I have only one network card -- I do.
I am sure that I need to change something in the router setup but I'm not sure how or what to do.
The cable is a non-static IP, and the router is presently set up to assign IP's to the PC's hooked to it.
Anyone with a similar setup get it to work?

Any help greatly appreciated?

I can only guess at what you are sayign here, it makes a little sense - perhaps?

One of the IPs is your ISP address and the other is the private IP maybe?

I think you are saying you are running NAT and hiding your local IP address. It is possible that your PC is putting that IP address into a data packet and that the datagram is using the ISP address. Many programs do this and it is an example of a poor design and there really isn't much you can do about it without a sophisticated router that can replace information in a packet based on the content. Enterprise routers can do this but generally not personal routers.

What specificaly was the error? Were the IP addresses identified? Maybe I missed the boat here.

I would try connecting your PC directly into the cable modem... This will tell you if it is your cable modem/ISP or the Linksys giving you problems. If it is the Linksys here is some info that helped me with gaming.....

=======================

Games over the Router
If playing games like Quake or Battle.net, port 27960 must be opened in the router's advanced feature. Refer to the manual and the help button on the router on how to open ports.

============

DMZ Host
The DMZ Host setting allows one local user to be exposed to the Internet to use a special-purpose service such as Internet gaming or Video-conferencing. To expose one computer, enter the computer?s IP address and click the Apply button. Inactivate DMZ by entering a zero (0).

UNCbeatem!

Sorry the message is so confusing -- basically, this is a problem at Jane's Combat.net.

I log in to do dogfights over the internet -- at some point the software assigns you a callsign (ID) based on your IP address -- for some reason it assigns my callsign twice -- my IP identified on my machine within Jane's WWII Fighters itself is correctly marked as the one my router assigns my PC.

For some reason, the combat.net "sees" two IP addresses -- I don't know what they are.

I hope this might help.
