I've been trying to portforward for TF2 lately. Supertoxic told me to portforward to 27015; that didn't work.
So then I googled it. (lol) On some Valve blog, someone said to portforward:
27000-27020 (tcp/udp)
27020-27050(tcp/udp)
27015(tcp/udp)
That didn't work either.
Yes, my firewall is letting tf2 by.
Any help?
