first you will need to create an access-list:

(config)# access-list 101 deny tcp any any eq 23
(config)# access-list 101 permit ip any any

then from the interface configuration mode, you will need to apply the
access-list:
(config)# int s0/0
(config-if)# access-class 101 in

Subject: Cisco IOS question

On my cisco 3600 router. How can I disable telnet into
serial 0/0. I do need to leave telnet open on
FastEth0/0 but I don't want anyone to be able to
telnet in from the outside.

Any Ideas?
Thanks
