Enter Filter Rule Number (1-6) to Configure: 1

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).

Figure 24-13 Sample Filter Rules Summary - Menu 21.1.3After you have created the filter set, you must apply it.
