    Hello,

    For a school network, we have multiple WAN connections and multiple VLAN LAN networks.

    WAN1 is fiber.
    WAN2 is a cable modem.
    Problem:
    WAN2 (the cable modem) fails when too many sessions are made over this line. The cable modem cannot support the entire school.

    Network Overview:

    VLAN01 (faculty, teachers, student computers)
    VLAN02 (cellphones, guest network)
    Desired Setup:
    VLAN01: WAN1 (primary), WAN2 (failover) → Primary: Fiber; Failover: Cable modem
    VLAN02: Cable modem only, but should lose internet completely if WAN1 (fiber) goes down.
    Issue:
    I haven't found a way to disable internet access for VLAN02 when a WAN connection (that it doesn't use) goes down.

    Any help would be greatly appreciated!

      Not clear, why you want to realize this behavior.

      The cable modem cannot support the entire school.

      Did you mean, the fiber doesn't support the entire traffic?
      Otherwise, this makes no sense for me.

        wan1 fiber is the most stable and fastest connection. 1gbps up/down
        wan2 cable is a more unstable 1gbps/50mbps connection.

        vlan01 faculty has to have the fastest connection both up/down
        vlan02 guest can live with cable modem.

        now cable the cable modem goes down about 20-40 times a year. And cannot support entire campus (amount of sessions, isp problem)
        fiber we only have this school year has been down once because of road works.

        faculty schould be guaranteed online so fiber -failover to cablemodem.
        Cablemodem cannot support total campus so guest network should be disabled in this event.
