Umm.... i have a problem with my router rite now, it doesnt let me host games in Gears of War or Crackdown for that matter, i checked why and apparently its my ports. There on strict. Ive had them open before, my router has a setting to turn of the dsi firewall but even if i turn it off the ports are only open for an hour or so before they go back to strict. Ive tried portfowarding but i think iam doing it wrong. IS there a way to fix this problem?
First find out the ip address that the router has assigned to network card. Then go into the router settings and look for the DMZ option. Lastly, enter your ip address into the DMZ and hit OK. This will put you outside the firewall and leave you vulnerable. It is however, the simplest solution.
