Since day 1 I have only had 4 ports opened.
Luckily my router supports the UDP/TCP option so it doesnt matter which protocol they are using.
However, I did set them up for incoming traffic to be redirected to my server ie "Port Forwarding" as Netgear call it.
Also running it on a win2k workstation (none of this annoying winXP nonse!).
Oh, and if I run gamespy on the same PC as the server, I cannot see the server on the gamespy list, but can still connect.... I guess it just uses & therefore blocks the ports.
Um, while I think of it.... dont tick the LAN option too!! As it doesnt allow both, its an one or other jobbie.
