ASA SSH Behaviour

Hi all,

Can anyone tell me why ASA is unable to change its SSH service port and besides that it is telling its OS on simple telnet to port 22?

I think this is very frustrating and I was hoping that Cisco will change this behaviour on the 8.4 version of ASA.

telnet 192.168.X.X 22

SSH-2.0-Cisco-1.25

I know SSH could be restricted only to ssh allowed hosts, but I do not like doing it this way.

Do you have any suggestions on this? How can I change SSH service port (some kind of NAT) or mask default ASA SSH responce?

Thank you in advance!

ASA SSH Behaviour

Hi Kimby,

Unfortunately, it is not possible to change this behavior on the ASA. If you control another device in front of the ASA, you could use static PAT to allow users to connect on a different port.

If this feature is important for you, I would encourage you to contact your Cisco account team and request that they file a product enhancement request to allow this functionality in the future.
