I'm stumped. We've allowed it through our firewalls, even disabled our firewalls, and I even forward the ports for online play despite trying to play on LAN. I just can't get these two machines to see each other in LAN games, but another thread confirms that it should work fine between two GOG copies of S3. I know the computers are connected through the LAN because they can ping each other through their local addresses just fine. Has anyone had any experience setting it up? Am I supposed to be putting something in the "Host IP" box?

yes you need to put the hosts ip adress in there and then search for games.

That's what I thought I should do, and I've tried it again but I still can't get a connection. It must be something stupid I'm doing because Populous 3 and Master of Orion connect on the LAN just fine. I'll try hosting on different computers for now and see if that makes a difference

Thanks for the response!

We just decided to use GameRanger and run it over the internet and it ran beautifully.
