OK, so here is what I've surmised...
Both games are on our home network, so I attempted to connect them via LAN network (they are actually connected to the same LAN network, but via a router). RESULT: We can't even see each other to connect to a game.
I also tried connecting each of us individually to a random online game. RESULT: EUREKA! It works! In BOTH cases! But we still can't connect to EACH OTHER! (Frustrating as hell!!!)
So I then tried disconnecting one of the computers from the ethernet and connecting via WiFi to see if that didn't change anything, and nope. Same result.
So I'm thinking maybe the problem is in either computer hosting (I tried hosting on both computers). OR maybe the game won't connect two different games on the same IP address?
Your continued help would be greatly appreciated.
P.S. Attempted to do the port thing, except when I enter a port and save, when I go back in, the port is no longer there.
