Choose routing mode when you need to filter packets between multiple networks connected by a Solaris-based system. A system in routing mode acts as both a router and a firewall. To use proxies or to install additional network services on the Screen, the interfaces must be configure in routing mode. Routing mode requires at least two exposed IP interfaces.
Be aware of the following considerations when operating in routing mode:
As with any router, the Screen is situated between subnets.
Adding a new router to your network can require a reorganization of your network and renumbering of your hosts.
Solaris software IP stack on the Screen's filtering interfaces exposes an IP address, as opposed to a stealth configuration that does not.
