Summary of Multi-WAN Requirements

This is a brief summary of configuration changes necessary for a fully implemented multi-WAN setup:

• Create a gateway group under System > Routing on the Gateway 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 gateway (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

These topics are covered in detail by the following sections.
