I recently purchased a new modem (Dlink DSL 2520u) since my old one broke down. I now use this modem + a wireless Netgear WGR614v7. Ever since I changed modem, I'm unable to connect to DotA 2 game servers, and I get a error message "Disconnected from server"
I did not have this problem with my old modem connected to the same wireless router. But after a bit of research, I found out that my new modem is even acts as a router, coz of which I now have multiple routers running. I tried port forwarding and even enabling DMZ, but it has still not been of any help. How do I make sure that the right ports are being forwarded since I have an online tourney coming up soon and I'm really desperate to get this working again!

Thanks!
