Figure 61 Example Filter: Menu 21.1.3.1
When you press [ENTER] to confirm, the screen shown in Figure 62 is displayed.
Note that there is only one filter rule in this set. The screen 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, whether or
not there are more rules to be checked (there are none in this example).
