So I forwarded ports for world of warcraft and Garena on my router, do I have to forward the same ports in my modem?

The quick answer is no. Unless you have a integrated router in the modem.

Normally, no. I have seen some cases where the network was set up as double NAT in which case you would need to DMZ the router. This seems to be common with AT&T DSL and Hughes Net internet where the modem does not support a "bridged" mode and has a built in firewall.

Sir, what do you mean a modem that is "bridged"? Care to elaborate on that sir?

Basically, bridged means your router becomes part of the ISP's network. For example, in a bridged network your modem would "pass-along" the public IP address given by the ISP to the router. If it's not bridged and double NAT is being used then your modem is assigned the public IP address, and the modem assigns the router a private (for example, 192.168.0.2) IP address. Your router then assigns your PC a different private IP (ex: 192.168.1.2) and since it's going through two "layers" of private IP addressing (NAT) it's "Double NATed".

The easiest way to tell if your connection is bridged or not is to look in the router's control panel and see what type of IP address has been assigned to it's WAN interface. If it was assigned a 192.x.x.x, 10.x.x.x, then it's not operating in bridged mode and may be double NAT'd.
