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). 

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).

this set.
