rawmilk905: I tried port forwarding, something NWN required that I do for hosting over the wireless connection, I am hoping that fixes it. According to a web seach, the port Overlord uses is 3074.
JudasIscariot: For LAN play, no. Unfortunately, I have dug a bit deeper and it seems like multiplayer over the net may be a problem. Sorry for the confusion.
rawmilk905: Could you possibly give a more detailed explanation? The servers are now offline? They don't work with the GOG version? You aren't authorized to distribute unique keys?
As far as MP over the net goes, I *think* it was an issue with the official servers not being online but I am not 100% sure as I am at home.
If you want to try multiplayer, I believe Hamachi is your best bet.
