Remote Administration via Telnet

We've got a T1 coming into a cisco 2610 that is then connected to our PIX 501. We have the router configured to let all traffic through and then we block it at the PIX. My question is, this leaves a hole open on our 2610 - that is, outsiders can telnet in and could hack our id and password to easily get access to the 2610. Is there a way to turn off remote administration as a whole? (Make is so that all administration must transpire over the console port.)

If not, whats the easiest way to set up the 2610 to let in all traffice, but the traffic on the telnet port?

Re: Remote Administration via Telnet

To block telnet access, you can use something called an "Acess Class"

You first create an ACL ie:

router(config)# access-list 1 deny any

Then apply the acl to the vty:

router(config)#line vty 0 4

router (config-line) access-class 1 in

Save the config..that's it.

Good luck!
