Set up dual wan

  • I have 2 cable modems from the same isp.

    modem 1 has ip of 
    modem 2 has ip of
    both have a subnet mask of and a defualt gateway of

    how would i set this up so load balance will work correctly with fail over?

    I already have my pfsense box up and running with 3 nics (1 configured as WAN1, 1 configured as opt1WAN2, and one configured as LAN)
    I have put the static ips in for the 2 WANs as well.

  • You'd have to put a NAT device on one of them since the gateway IPs are the same.
