Re: Unable to remote telnet

Hi dk

Do check the power status of the router?

Connect onto the console port of the router and check the status of the router ?

if everything is fine then check out for line vty config (telnet).

Re: Unable to remote telnet

There are several steps you need to take for this.

1) Check power to the equipment

2) Can you ping the address you are trying to telnet to (if you allow icmp)

3) Try ssh access

4) If there is power & you can ping, you will then need to find a way to OOB - console into the router as it is most likely an ACL issue

Things to check when consoled in....

1) Check the ACL that is applied to your line VYY ports

2) Check to see if there is a transport input statement applied - you may be restricting access to a certain type

3) Check the ACL applied to your interface ports (traffic passes both the VTY & the interface)

Re: Unable to remote telnet

If you can ping it but cannot get a telnet prompt, then maybe the router has the default "access-class 23 in" on the vty. Remove it.

Re: Unable to remote telnet

It is your ACL that is causing it. instead of doing

access-lit 101 permit ip any any

do

access-list 101 permit x.x.x.x x.x.x.x (whatever your LAN subnet is)

That will fix your issue.
