If i create a D1 or D2 game and then have my brother join it (who lives in my house) using the ip 10.0.0.6 (my router based ip) can a 3rd person who lives wherever in the world join it? Using my external IP address? (68.254.148.170).
I tried it once but it did not work.. any ideas? I hope Im just missing something.
I dont think they could because your game is not broadcasting over the net. Unless you use TCP and start a net game, have your buddy in your house join it and then your other one from anywhere else join. If you use IPX, it won't work.
Well.. for D1X-Rebirth (and soon D2X-Rebirth) it should possible...
Your brother joins via local ip, while someone else joins via the external IP (if the UDP port is correctly routed).
