SunScreen 3.1 Release Notes

State Engine ether

When running in stealth mode, SunScreen supports the passing of Ethernet packets that are not IP-based. Examples of these types of packets include Novell IPX, AppleTalk, DECNet, and others. The method for passing these packets is based on the undocumented ether state engine.

To pass such packets, you must define a new service using the ether state engine, and must know exact Ethernet frame types that are used by the non-IP packets.
