replacing the SSH connection port

Arturxr — Wed, 01 Oct 2025 12:50:42 GMT

Good afternoon, we want to replace the SSH port from the standard 22 to another one. We perform the following actions:

# sed -i 's,^#Port 22$,Port 2200,' /etc/ssh/sshd_config

# service sshd restart

Port 2200 is connected, and everything is working, but only until the Check Point is restarted. As soon as we restart the Check Point, the changes in the /etc/ssh/sshd_config file return to their original state. Tell me, have you changed the SSH port? Was it possible to solve this problem?

edit/backup /etc/ssh/templates/sshd_config.templ and run /bin/sshd_template_xlate < /config/active

but every Jumbo update / upgrade change will be reset.
