Try forwarding 27011
I am pretty sure that is the Master Server Port.

Adding master server 69.28.151.162:27011
Adding master server 72.165.61.189:27011
Connection to Steam servers successful.
VAC secure mode is activated.

CA firewalls are a pain (all ca prducts are a pain) if ur running XP or Vista uninstall the firewall and use the built in one.

Been useing the built in XP SP3 firewall in my server and AVG 8 free and have had 0 problems from day 1
