Using 2 ISPs - each for a specific vlan but still enabling failover TZ670

edited October 2022 in Entry Level Firewalls


I typically have all the VLANs on each lan port - e.g. x0 will have vlan 10, 20, 30, 40 and 50.

I have ATT on X1

I have Spectrum on x2

My vlan 10 is for wired data, vlan 30 is for private wifi and VLAN 40 is for guest wifi

I want to have VLAN 10 and 30 on ATT

I want to have vlan 40 on Spectrum

I"d also like to make it so if ATT or Spectrum stop responding on the LB pings, all traffic is routed on 10, 30 and 40 to the functional ISP.

    @boe Failover & Load Balancing isn't flexible enough for that job, but it can be done with Policy Based Routing (PBR).

    Just create a two Route Policies looking like this:

    Source: VLAN 10 + 30 Subnet
    Destination: Any
    Gateway: X1 Default Gateway
    Interface: X1
    Metric 1
    Source: VLAN 40 Subnet
    Destination: Any
    Gateway: X2 Default Gateway
    Interface: X2
    Metric 1

    It'll automatically falls back to the Default Routing if the WAN Interface is not up, maybe you need to put a probe on each Route for logical Interface Monitoring.
