\are you sure you have the right ports open ?
you posted this in the other thread as your ports
but the ports for tf2 are
TCP Ports
27020-27050
UDP Ports
1200, 27000-27015
as far as i know, im the tech , the lads not playing the game right now so i cant check his current settings...
so those upnp opened ports are for something else.....
if i remember right, You can find the ports you need by typing
status in the console and looking at the ip address info.
and OC that 192.168.0.3 is your current fixed or router given LAN IP for the PC your running TF2 on!
