Static routing provides a fixed path for data in a network. When a server on a network is connected to additional networks through a router, communication between that server and the remote networks can be enabled by specifying a static route to each network.
Static routes are set up in a routing table. Each entry in the table consists of a destination network address, a gateway address, and a subnet mask. Entries for static routes in the server’s routing table are persistent, meaning that, if a server is restarted, the route table preserves the static routing entries.
The NAS server supports gateway, network and host static routes. The Default option sets up a gateway and does not require a destination. Select the Network option to set up a route to address all of the computers on a specific network. Select the Host option to address a specific computer on a different network. The maximum possible number of static routes is 127 (default gateways also count against this total).
In most cases, for IPv6, it is not necessary to statically configure gateways as they are automatically discovered through the received router advertisements.
