I am trying to connect to the outside interface of a Cisco ISR 1100 with SSH. If I do a remote session with the user at the site - I can SSH to the ISR at the inside address. But if I try to ssh to the external interface of the ISR I don't even get a login prompt. There is no ACL on the outside address. There is an ACL on vty 0 4 but it includes the source address I'm coming from and I even removed that ACL to prove the point temporarily.
Any other suggestions with regards to getting ssh to work on the outside interface as well as the inside? Is there a good debug that could help?
I have ip http secure-server in the config.
