SSH on Astaro 3.2

If I want to use SSH to access the firewall and also need SSH access to my server (via NAT) on the default port (22), I need some way to change the port number for SSH on the Firewall itself.

Does anyone knows how this can be done?

Hi danielC,

use DNAT on port (e.g.) 2222 on the firewall and as destination port 22 on your server IP.
Do a 'ssh -p 2222 ServerIP' for connect you server through the firewall.

Thanks for the reply but for some reasons (external people need to contact the server from different kinds of software and it would not be easy to ask them all to change the port) I cannot change the deafult port for the server so the only alternative is to change the SSH port for the firewall itselves.
Is there no way to accomplish this?

danielC,

edit /etc/sshd_config, set the port to whatever.
Disable SSH in WebAdmin System/Settings it
opens a useless port 22 to the firewall.
Define your new port in services and allow access
to your firewall interfaces!

read you

I have forgotte to say that you have to restart
the "sshd /etc/rc.d/sshd restart"
