Hi all,
I config a dynamic access-list for dynamic control telnet access. But when I connect to the host (my host is 192.168.0.1), there is the following prompt:
List#130-testing already contains this IP address pair
[Connection to 192.168.2.1 closed by foreign host]
And the following is the running config of my remote host:sh run

The way I have seen lock and key (dynamic acls) set up, is permit telnet traffic to an interface address, then permit the traffic you want to allow through your router. Take a look at the example in the following link:
