Summary of Multi-WAN Requirements

Before covering the bulk of multi-WAN specifics, here is a short summary of the requirements to make a fully implemented multi-WAN setup:

  • Create a gateway group under System > Routing on the Groups tab

  • Set a failover gateway group for the default gateway as described in Managing the Default Gateway (Technically optional but a best practice)

  • Configure the DNS Resolver or Forwarder for Multi-WAN, starting by:

    • Use a failover gateway group for the default gaetway (DNS Resolver in default resolver mode)

    • Set at least one unique DNS server for each WAN gateway under System > General Setup with a gateway set (DNS Resolver in forwarding mode or DNS Forwarder)

  • Use the gateway group on LAN firewall rules
