Multihomed ISPs

  • Okay, so to start, the problem I'm looking to solve is getting a faster upstream. Currently have DSL. Ordered residential cable (business class was price gouging). Since cable might have a cap, I was wondering if the following was possible:
    1. DSL (A) - no cap.
    2. cable (B)
    Have a router, or build a 3 nic pc, that can send all outgoing traffic through B, but have the originating address of A so that all incoming traffic comes back in on A.
    I was told this was BGP and that pfSense could do this. Is this correct?
