Port Forwarding Please?

[iLoVe.cF-]

6112-6119 udp/tcp 4000 tcp to my comp keke, rules, allowed.. hmm.. UPnP installed.

Doesnt work with all gamers on battle.net(Starcraft)

I still CANT play with more than 1 player usually, in some rare instances does this actually work, what is wrong ? , something with states, firewall settings ? hmm ? :S
