Router Ports? (MP connection problem)

[Zephaus]

Has anyone found out what router ports need to be set in order to host a multiplayer game?

I've tried hosting a friend over the multiplayer server, but we can't connect. I'm assuming my router is blocking him (since it does in other Civ games unless I change the port settings). I can't seem to find any listing of the ports CTP2 is communicating through. Any ideas?

I did see a rumor that there were problems with two people running XP connecting to each other, but I never saw any confirmation that that was anything more than a rumor.

Thanks for your help,

If you both have XP/2K then that is very likely the cause. I play through a router and always connect fine but I do have to reboot to win98 because I can never connect with someone else on XP/2K, even without the router I couldnt.

If I have interpreted the Anet code correctly, all players will start by setting up a connection to UDP port 21157 of the server. This connection will be used to distribute address information to/about the players (using some randomly generated port numbers in the range from 21100 up to - including - 21299).

Thanks, we'll give this a try!

Tried those port settings, and my friend still can't join the game from the lobby, even though he can see it.

I assume it's likely the WinXP issue. We both tried running the game in Win98 emulation mode (from XP), but that didn't seem to solve the problem either.

Perhaps we'll have to wait to see if there is a solution in the open source code version...
