1 if you don't have other routers or gateways on your lan, you can ignore the static routing page completely.
2 if your lan has other gateways and routers, you must configure the static routing screen as described below. you also need to configure the other routers.

if there is an entry or entries in the routing table with an index of zero ( 0 ), these are system entries. you can not modify or delete these entries.

configuring other routers on your lan
all traffic for devices not on the local lan must be forwarded to the load balancer, so that they can be forwarded to the internet. this is done by configuring other routers to use the load balancer as the default route or default gateway, as illustrated by the example below.
