Hi all,
When I run my 2wire DSL modem on DMZ mode(all ports open),my game server (A6)displays my external IP address (76.xxx.xxx.xxx).Great!!.
But when I set the ports manually (i.e. 2300 in modem),I only display my local IP (192.xxx.xxx.xxx).
I searched and looked all over and can't find he answer to.....
What ports do I need to open on my DSL modem.
Please include All possible port #'s TCP/UDP that I can try as well as the Dplay and DirectX port #'s.
Thank You
P.S. I researched this extensivly and am asking for your help as a last resort as I'm out of ideas. Thanx again.

On my router, I had to forward the following ports:

2300-2400 TCP and UDP
6073 TCP and UDP

Why you have to forward that many ports? Ask Microsoft, as 3DGS is using DirectPlay, a component of DirectX:

Still, my game server always displays my local IP (192.168.xxx.xxx). From my experience, this doesn't lead to any problems. People can still connect to your server from the internet, even if it does not know it's external IP.

Thanx SchokoKeks,
I have been to that page and thanx for confirming the 2300-2400,6073 port forwarding.When I ran a port scanner while connected and saw a bunch of open ports in my game listing.I didn't think I had to open em all but wasn't sure.
Well,happy coding to ya and Thanx again.
