On a NAS server, interfaces can be configured to enable communication between the NAS server, client, and external services. The system automatically creates a local route when an interface is created. This directs traffic to the local subnet through the interface that’s local to that subnet. If a default gateway is entered, a default route is also created. This directs all non-local traffic to the default gateway, which forwards it to other networks. In addition to these system-created routes, user-defined static routes can also be created.
In addition, starting with OE version 4.1, static routes can also be configured to determine where to forward a packet so that it can reach its destination. Static routes can be configured for both IPv4 and IPv6 interfaces. Each NAS server interface has its own independent routing table with up to 20 routes.
Using static routes enables the NAS server to access a destination using a specific gateway and interface. For example, complex networking environments may leverage multiple gateways, with each gateway enabling access to a different subnet. In this scenario, static routes must be configured to ensure packets are sent to the correct gateway for each subnet, instead of using a default gateway.
Static routes can either be a host or network route. A host route is the most specific type of route, which is only used when traffic is sent to a specific IP address. A network route is less specific and is used when sending traffic to a specific subnet. The system uses the most specific route available. If no host or network routes are defined, the default route is used (if configured).
