Multiple gateway balancing/failover with just one wan

  • hi, I'm trying to setup pfsense to balance line 1 and 2 and fail over to the backup line by using just one wan interface

    the load balancing works fine and the failover works as well if I disconnect the cables to the routers, but I'm not sure how to configure it with an external ip to monitor
    I used line 1 as default gw on the WAN interface but if that line goes down pfsense can't ping the others monitor ips as well so all gateways are marked as offline

    it would be even better if it was possible to do this with just one WAN interface(no LAN) since I don't need the firewall just the routing
