Thanks. We'll let you know when a new response is added.

You sure can – but you first have to have configured the VTY lines (in Cisco devices) to allow the router to accept telnet sessions. That would look somewhat like this:

Router(config)#line vty 0 15
Router(config-line)#password (your password here)
Router(config-line)# login
Router(config-line)#exit

Without those lines configured, the router will reject any incoming telnet connections…

    You can telnet to ANY layer 3 interface with an ip address that meets these two requirements: 1. The host subnet must be advertised out by the WAN protocol. 2. If your router is using TACACs, you must have the following command: tacacs source-interface <source ip address of interface for telnet/ssh>
