hello I small problems I Cisco router 800 serials now I remote wants work by means of SSH and telnet now are my question how can you this do?
who can help me
I don't understand what you mean.
do you have a copy of the router configuration? I can check and let you know what to add/change.
sorry, i don't quite understand what you mean.
Telnet locally works, however, telnet from external is timing out?
Are you getting the password prompt when you try to telnet from external? If not, then there is probably access-list on the interface that blocks telnet, OR/ under "line vty", it's only allowing internal address range.
You should be able to telnet to the router on the WAN/external ip address remotely if telnet is not disabled.
For SSH, you have to generate RSA keypair before you can SSH to the router. Here is the sample configuration for SSH:
Hope that helps.
