CWP comes with the OpenSSH server. This is using by default port 22. CWP doesn’t modify this at installation time but notifies you to change it as soon as possible. The message looks like:
WARNING: Security vulnerability! Your server is using default SSH Port 22, to make your server more secure change SSH port in config file /etc/ssh/sshd_config and in CSF firewall ! After changes are done don’t forget to restart SSH and CSF Firewall.
