I want to use Squid as a proxy/cache for web traffic via a cable modem with a static IP. I also have a T1 line that I want to use for gaming traffic.

Is it possible to set it up so that all web traffic, including FTP, goes through the Proxy/cache via a Squid server and the cable modem while all other network traffic uses the T1? I want the bandwidth of the T1 to just be used by online multiplayer games.
