I am unable to connect with my friends when trying to play a game online, but we can connect to other servers, like in Serious Sam. I have also played on MBL servers. I tried with both friends having the same network(ptcl) and a different network(maxcom). I also used Hamachi but that doesnt seem to get me anywhere either. I have tried the games Tiberian Sun, Serious Sam, Generals and Rise of Nations. I cant seem to figure out the problem. Any help would be appreciated.
