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).

After you have created the filter set, you must apply it.

1Enter 11 in the main menu to display menu 11 and type the remote node number to edit.

2Go to the Edit Filter Sets field, press [SPACE BAR] to choose Yes and press [ENTER].

3This brings you to menu 11.5. Apply the example filter set (for example, filter set 3) in this menu as shown in the next section.
