How to open ports on my Router? My router is MTNL 450TC1 Please help !


So the problem is that i want to open ports on my router because i want to setup a server for Call Of Duty 4. No one outside my LAN can connect to my server (they say their connection times out) so i think i've not opened the ports correctly on my router.

I also used this utility to find out if my ports were really open and none of them, even the common ports, came to be open. All of them were closed.

I dunno, is it a firewall problem? Cause i've not disabled my firewall.

Here's a pic of my router modem's page and all the settings i did to open the ports -

Please help guys :(. I've been trying to find the solution since 1-2 weeks now :(.
