if changing SSHD port do it via centmin.sh menu option 16 which will first prompt for default 22 port and then prompt for new SSHD port

I'd change SSHD ports especially if on OpenVZ as you're limited by how many IP addresses CSF Firewall can handle compared to Xen or KVM which have IPSET kernel level and CSF IPSET support to handle large number of IP addresses

Where possible, I stick with KVM or XEN VPS because of such stuff like this.

 

that's good thing

 

i like to keep port 22 for a while and gather up some bad ips to block before changing ports hehe
