I have had my server running on my end for quite a while, through my external (online) IP address, as provided my ipchicken.com
Thing is, I have just tried having a friend try to get on, first from my house, and got "Unable to connect due to server maintenance or network congestion".
I thought it may just because a garble due to it being on the same router, on the same internet connection as me, which can't handle a higher load well than 2-3 games running at once. So considering I was running a server, I though "ok, just a glug, try at his house".
So we went to his house, (computer still at home with server running) and still get the same issue.
He is using the same client as me. In fact, I gave him the link, and put the copy of my oem.dat/ini myself.
My computer is behind a DMZ, and I even disabled my firewall for it. My AntiVirus is AVG, which doesn't block ports, and I can run this game from my own computer (again, IP address *IS* set as told from IPChicken.com), and it IS a static IP by nature of my ISP.
Thoughts please?
