Routing Interface

Routing interfaces have one or more IP addresses and route packets using the standard IP routing mechanisms in the operating system. Each routing interface is connected to a different IP network just like a standard IP router. In terms of network placement, a Screen with routing interfaces replaces a router. A routing interface can also receive administrative traffic from a remote Administration Station.

Connections to and from proxies can only occur through ROUTING interfaces. Thus, to run proxies or if you want to install additional network services on the Screen, you must configure the Screen to have at least one routing interface.

Use routing interfaces to:

• Replace an existing router

• Control packet flow between different IP networks

• Receive administrative traffic for the SunScreen configuration

• Install proxies or other network services on the Screen

A Screen with routing interfaces does not need a separate admin interface, because the administrative traffic can come in through one of the routing interfaces. If Screens are part of an HA cluster, they each must have a unique HA interface for the dedicated HA heartbeat network.
