Heh, looks like it won't be so easy.

Basically, me and my friend just can't see each other's games on game list screen. Both on 'FSU Media VPs 4.4' mod and retail FS2 (launched via knossos). We see each other in lobby, but hosted games (no matter who is the host) are not visible.
We tried both 'FSO 21.0.0' and 'FSO MPBETA 1.1.0' builds (with FSU Media VPs) but with no success.
Also, we tried to play a non-PXO multi using our IP adresses - still nothing. We can chat on lobby, nothing appears on the game list.
Is it the same reason as on 'original' PXO, when only some ppl were able to host without port-forwarding-magic tricks? If you suspect/know the problem, (and, hopefully, solution

), we will be glad for any help. Of course we will share the times and dates when we're gonna play, so maybe we can fly some big juicy 8-players co-ops (ToF, Vegas).

Also, I have one more strange problem - I installed mods 'FreeSpace 2 Multiplayer Coop Up' & 'War Games', but they just won't launch. When I click 'Play', Knossos displays 'FSO is launching' for one second, then 'FSO is running' for another, then just nothing happens.

When I check "FSO Setting" for those mods, I see only the build (FSO MPBETA 1.1.0) - 'Custom flags' and 'Full command line' fields are all empty. If I chose the same build (FSO MPBETA 1.1.0) for FSU Media VPs, the game starts and works normally, and the standard set of 'custom flags' and 'full command' line is there. But this is secondary problem - I'm going to reinstall the whole game today and see if it persists.
