A few friends and I installed Star Wars Battlefront II onto our machines via GOG.com.
We tried booting the game and creating a multiplayer game and then joining that way but we didn't see one another's games in the lobby browser section.
We then booted GameRanger, all joined the same room and the host clicked launch. The host gets into the game, however the others are left stranded with a message saying something like Busy, Joining ... then just shows the seconds count.
After about 15/20 seconds it just stops and that's that. No one is able to join one another in a (LAN) game of SWBF2.
AoE2 and UT2004 seem to work via GameRanger or straight up LAN creation within the game, so I'm not sure our network is restricted.
How can we go about debugging/fixing?
