Advanced > Routing
Typically you do not need to setup static routing since the ESR300H usually has adequate routing information after it has been configured for
Internet access. You will only need to set up static routing if the router is connected with a network under a different subnet and you need the static
routing to allow network connection in two different subnets.
Note: To enable a static routing, you need to disable the NAT function.
