I've enabled UPnP on Pvc0 and on the 'Virtual Server' page i've defined a user rule named "CallofDuty2" that opens the following ports:
The router has NAT, DHCP, DNS configuered.
It's a modem and a router. So it has the configuration of our ISP, and the only thing that it does more is provided, each pc plugged into it, an IP address.
The game appeares like it's asking for permission to connect to to Internet. And after 1 min i boots up. When i close my connection to the internet and my router, it boots up in no time.
I've noticed that UPnP wasn't enabled the first time but now i have.
Still not working but i thank you for the reply.
