AppleTalk Get Zone List filter rules filter what is seen in the Chooser of 
Macintoshes attached to the network to which the rules are assigned. The 
example would: deny all zone names from networks 1-10; permit the zone 
name "Engineering;" deny the zone name "Sales;" permit all networks not 
equal to 100; and permit everything else.

deny net-range = 1 10 

permit zone = "Engineering" 

deny zone = "Sales" 

permit network != 100 

permit

AppleTalk RTMP filter rules can be used to limit the network numbers that 
are allowed into the routing table or to be advertised from the device. The 
example performs the following actions:  deny networks with a number of 
100; permit networks between 200 and 300; deny networks numbered greater 
than 301; and permit everything else.

deny network = 100 

permit net-range = 200 300

deny network > 301 

permit
