How to change SSH port and firewall rule?

Hi, I have set up a different port for SSH(same way as it is described in the deprecated article) and custom firewall rule [TCP, all IP4/6] limited to the same port. I still can’t get connection[ssh: connect to host xx.xx.xx.xx port xxxx: Connection timed out]. What is the problem?

Helo LampreyOne,

Thanks a lot, for your tip. I’ve been blocked to acces my droplet after the FIREWAL installation. Then your solution was my salvation.

To change the port ssh works on, edit /etc/ssh/sshd_config and edit the line “Port 22” to be a different port. Then restart sshd (“sudo service ssh restart”) You can then test whether ssh is working on that port with “ssh localhost -p 1234” or whatever your new port is.

If that works, but remotely doesn’t work it’s probably the firewall issue. How do you have your firewall set up? The firewall from Digital Ocean’s control panel? UFW? IPTables?
