1st, they actually tell us what ports need to be opened:
[quote:841df]TCP port 12203 (default ), 12204 - 12218
Master UDP port: 12300
Server UDP port 12203 (default), 12204 -12218
Note: you will need TCP and UPD ports 6667, 3783,27900,28900.29900.29901.13139 amd 6515 open to use Gamespy to connect to Internet servers[/quote:841df]
2nd
[quote:841df]MOH:AA:S supports and plays all MOH:AA maps as well as MOH:AA:S maps. However, people running Spearhead my not join servers that were started with MOH:AA and vice versa. If you wish to join an MOH:AA server, please QUIT Spearhead and re launch the game using the MOH:AA shortcut[/quote:841df]
I have not been able to find any info out ( from any readmes) about customizing the game via a server.cfg file. hell, you don't even get a server.cfg file after you install Spearhead.
