Single WAN + Single LAN Failover

  • Hi,

    I have a single WAN and single LAN terminating on my pfsense. My WAN is PPPoE interface with Dynamic IP address and my LAN is I have another server with different ISP landing on it. I want to setup a Failover mechanism were if my WAN interface goes down I want to get internet from my second ISP landing on my different Server. Please help me to find a solution on this issue.

    If you add the other ISP-connected device as a gateway on LAN, it should be possible to use gateway groups for that. You will also need to check the box under System > Advanced, Firewall/NAT tab to bypass the firewall rules for traffic on the same interface (and perhaps add manual rules, see )

    The other device would also need to perform NAT for the local LAN as well.

    It's a bit ugly and error prone, but in theory it should work.
