Routing Interfaces

Routing interfaces have an IP address 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 receive remote Administration Station traffic.

Connections to and from proxies can only occur over routing interfaces. Thus, to run proxies or if you want to install additional network services on the Screen, you must configure the Screen with routing interfaces.

In summary, use routing interfaces to replace an existing router, to control packet flow between different IP networks, or if you want to install proxies or other network services on the Screen.
