Pix doesn't allow telnet to outside interface, only ssh.

Thank you for reply, but i don't make this.

How do you configure this SSH on the Outside interface PIX ?

How do you enable SSH (aaa) on the PIX515 ?

And after is it possible from my C831 to access to PIX with SSH ?

i tried but i don't message error :


I tried with Putty SSH from my pc to interface inside PIX but it doesn't work too.

Best regards,

Do you have a line stating :

ssh outside


telnet outside

in the pix's config ?

Try this

aonnect from internal network and use the command "passwd" to create a telnet password. This will also enable the telnet from outside

hope this works
