I am hosting a Gameserver on my Windows 2003 Server 32 Bit Server. Due to some limitations of my ISP, I have to take 2 Internet connections in order to satisfy my bandwidth requirement. I am facing serious problems here.

The Internet is supplied using Wimax. I am given a POE and the RJ45 from both the POE (2 connections) are plugged into a Netgear 100mbps Switch and another RJ45 connects the server to the switch. I have tried to configure the IP addresses and gateway of both connections to the single NIC in the server. The IP series and the gateway of each Internet connection are very much different.

I know that this is not the proper approach, because alternate gateways are meant to be only for backup in case of main gateway failure and the usage of the gateways depends upon the metric (correct me if I am wrong).

I am planning to get a second PCI NIC so that I can connect each of the Internet connections into its respective NIC. If I use this approach, will I be able to accept connections on both NICs?

Also, please suggest any other alternatives that I might use.
