Hi,

Please check for any access list configured on the router

Please post your (sanitized) config ... or at least tell us what kind of error are you getting?

Does it "just not connect" (i.e. times out)? or do you get a message like "Password required but none set"?

Does the router work (aside from no telnet)?

Did you try one of the other addresses associated withthe router? Like, try the loopback, or Ethernet address instead of the WAN port address.

Let us know

no access-list, no loopback interface, line vty 0 4 is configure with password and transport input telnet ssh.

error which i get is just not connect.

ping work, and telnet work from inside network, but fron outside i cant reach destination...

You made it to the router. The router may have responded (probably did).

Do you have a software firewall running on your client? Has it been configured to permit the telnet traffic returning from the router? (or if the client is another router, is there an access-list on the local router that is blocking the return traffic?

Good Luck

Hello,

please post the access list used for NAT. If it is the kind of "permit ip any any", that makes telnet attempt to fail with recent IOS versions.

Hope this helps, please rate post if it does!

you stated you have it configured for ssh. does ssh work? i would suggest using that anyway. perhaps you have it only configured to use telnet from inside not outside aswell.

you will need something like this

telnet 10.1.2.0 255.255.255.0 outside

regardless of what you have in acl if you dont apply telnet to ouside it just wont work.

Hello,

this is about a router, not a PIX. Beside, the original poster may have lost interest in this.
