I got my desk top and laptop connect with a wifi router TPLink 340G and the router is connected with net via a wireless modem GIGASET SX682 WiMAX (manufacturer: Sagem).
Everything works fine except that I cannot port forward from any of the PCs. I opened ports on the modem and as well as the router and nothing seems to be working. But if I only connect the modem to my desktop or laptop port works fine.
I opened port for Call of duty 4 port it works when I connect the modem to my desktop or laptop but it won't work when its connected though the TPLink router.
What did I do wrong?
