Hey guys. So im trying to play COD 4 MP using gameranger but when i click on join it shows that "Firewall Problem : You appears to have a firewall or router that is blocking you from playing games".I investigated on this issue a little bit and found that i have to open UDP 16000 port in my firewall (or something like that) and i did that. but nothing seems to be working. BTW i tried disabling my firewall also. My ISP is Link3 and a TP-Link router.
Hope you guys can help me ,Thanks in advance guys
