i am trying to open ports on my firewall to play madden nfl 2004 on my PS2 they say that i need to open these ports
10500-10519 tcp
13505 tcp
3658 udp
7777 udp
1791, 1792, 9995 and 9996 udp
Ports 10500-10519 and 13505 are TCP and only for outgoing connections
Ports 3658 and 7777 are UDP and used for connecting to other users and playing games

this is what i have and i am lost as to why it willnt work any ideas i can play CS just fine and can surf and do everything else
