      I've read that it is possible by utilizing NAT routers.

      Anyone can show the step by step?

      TIA!

        What's there to explain?

        I have something like this. 2 ADSL from the ISP. These ADSL modem are bad, since you do IP passthrough and the address assigned to the WAN is such as

        IP: 33.1.2.3
        SUBNET: 255.0.0.0
        GW 31.1.2.254

        No issues, but connect another one and it's the same. Dynamic IP so it changes. Both IP start with same octet at times, e.g. 2nd WAN:

        33.99.2.5
        SUBNET: 255.0.0.0
        GW: 31.99.2.254

        See the issue?

        So you connect your WAN 1 to a cheap NAT router, set the LAN IP to e.g. 10.10.0.1/24
        So you connect your WAN 2 to a cheap NAT router, set the LAN IP to e.g. 10.20.0.1/24

        Issue solved! If your not sure what I'm saying read up on CIDR.
