Can I renumber the telnet port on the serial interface of my 3620 router?

I am wanting to renumber my telnet port on my router for security purposes but I am unsure on how to do this.

Hi,

This can not be done. You can use access-lists on the interfaces or an access-class on the vty interfaces to restrict access. You can also require logins and passwords.

If you add the 'rotary-group 1' command under the line vty config you'll then be able to telnet to port 3001 as well.
