Menu 21.1.3 - Filter Rules Summary

# A Type Filter Rules M m n

1 Y IP Pr=6, SA=0.0.0.0, DA=0.0.0.0, DP=23 N D F

6 N

This shows you that you have

configured and activated (A = Y) a

TCP/IP filter rule (Type = IP, Pr = 6)

for destination telnet ports (DP =

23).

M = N means an action can be taken immediately.

The action is to drop the packet (m = D) if the

action is matched and to forward the packet

immediately (n = F) if the action is not matched no

matter whether there are more rules to be

checked (there aren’t in this example).
