Defining Filters and Firewalls
Example filters
6-14 Preliminary January 30, 1998 Pipeline User’s Guide
These conditions define non-AppleTalk traffic. Note that AppleTalk has the
protocol type 0x809b. Outbound packets that are not AppleTalk packets will
be forwarded. Because all non-AppleTalk packets have now been forwarded,
subsequent filters can assume that a packet is AppleTalk.

AppleTalk “broadcast” traffic uses a multicast address. These conditions
specify the multicast address. Any AppleTalk packet that does not use the
multicast address will be forwarded.
