Q. Are you behind NAT? (Network Address Translator)
info: NAT allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network.
A. If you are behind a NAT, you MUST forward at least the following ports - 5911 udp, 5911 tcp, 13139 udp (although, to be safe, I would open all 8 ports as instructed in the Firewall sticky on the Forum).
Forward them to the Internal IP address of your machine (usually something like 192.168.0.2) If you don't know your IP address, post and I'll show you how to check it.
НА диай 604? Какой адрес у моего компа если в настройках сети все определяется автоматически?

Пропишите ip адрес у компьютера статически или настройте static dhcp http://www.dlink.ru/technical/faq_internet_40.php

А как собственно затем сделать форвардинг? Хотябы в каком меню?

Advanced->Virtual Server. Возможно проще будет поместить компьютер в DMZ (Advanced->DMZ).
