Access to ASA from outside SSH port redirection help

burleyman

Lets say I want to allow access to the ASA via SSH from one IP address on the outside.

I know you would just configure this.....

ssh 1.1.1.1 255.255.255.255 outside

now lets say I already am using port 22 for something else and we cannot change that.

How can I translate to another port so I can still accomplish what I need?

Would this work?

Lets say the ASA has the following IP addresses on the interfaces

Inside: 192.168.1.100

Outside: 1.1.1.1

Lets say I want to access the ASA via SSH but I can't do it normally because the port is already in use by something else. Could I just create this Access List.

Remote IP to access ASA: 2.2.2.2

access-list outside_in extended permit ip 2.2.2.2 255.255.255.255 192.168.1.100 255.255.255.255 eq 22

 

would that work

It is currently not possible to change the SSH port for managing the ASA.  You would need to configure a VPN connection to the ASA, configure an interface to accept managment traffic (management-access inside...where inside is the interface IP you want to SSH to).
