hi.
Firewall configuration for ability to HOST Starcraft games on Battle.net behind NAT.
best way is to use NAT only, no WRP/GDP
Port Range Configuration:
add 6112 UDP port for [Connections from Internet computers]
set redirection for that port to your local IP ex.(192.168.1.3)
switch ON option [Dont Translate source IP]
thats all, now u can Host Starcraft games at any time u want
for just joining other people games no configuration is needed at all as far as outgoing ports aren't blocked ofcorse :)
tested on Wingate 5.2.2
hope it will be usefull for others
