Cisco 877 telnet issues

weathermon

Level 1

Hi all,

I've been wrecking my brains all evening trying to sort this one out and I'm convinced it's an IOS bug.  I have another Cisco 877 with telnet working absolutely perfect from telnet via LAN (vrf) and WAN.  It's running c870-advsecurityk9-mz.124-15.T10.

 

The problematic 877 is running version c870-advsecurityk9-mz.124-24.T6.  No matter what I do, I cannot telnet into the WAN connection at all - I constantly get the message "% Connection refused by remote host" (I can telnet into the lan ip via the vrf perfectly fine).  Here's the running-config:

Hi your running a K9 try ssh see if its the same it should identify if its a bug or not that just effects telnet , is there anything in fornt of the router that could be blocking it , you should have an access-class on that vty port as its wan facing.

ip ssh version 2

ip ssh timeout 120

ip domain-name xxx

crypto key generate rsa [1024)

 

You could also try set it just fro telnet see if that helps

transport input telnet

transport preferred telnet

 

If you debug telnet is anything hitting it at all
