This problem has plagued me for quite a few days. We've already tried the addition of the suggested ports, the disabling of ZoneAlarm and the frame type setup (as was suggested by Blizzard techs). Nothing works. We're both on a LAN, shared DSL connection, have 2 IP addresses and 2 original CD's. The strange thing is that I re-installed Diablo II as an experiment, as did my friend, and we can both join each others games there on Battle.net. But... just not in Warcraft 3. We can both join OTHER peoples' games though, just not each others. It's all really strange, and that's not an option at the moment because we don't want to play the game with others at this point. Any suggestions or feedback would be appreciated on this. Thanks in advance.
