I’d like to change the ssh port on my panel. I changed it in webmin/servers/sshserver/edit config files. Unfortunately, I can’t log in to my server via ssh after port changing. I even added my custom port as allowed one in FirewallD and Usermin Cofiguration, but that’s not working too. I learned from other topics that I can fix this through Linux Firewall. But I do not have access to it. Can you help me solve my problem? Thank you friend. ---

Well that not a firewallD issue 🙂 how did you change to the port in sshd? Just here? ![image](https://cdn.forum.virtualmin.com/uploads/default/original/2X/a/aa94a642efa7ac9b4f2b6f3c2ff3cede74dbd570.png) this will show if its listening on the port `lsof -i:22` change to new port ---

Yeah. Change them back until you understand what you are doing. ---

Do you mean I should change it back to 22? As long as my ssh port is set to 22, I have no connection problems. ---

I think that’s why I changed it in Usermin or Webmin configuration, I thought that would fix my problem. ---

You’re trying to put ssh _and_ Webmin (and Usermin?) on the same port. That doesn’t make sense. ---

I changed them back to default… Webmin on 10000 Usermin on 20000 ssh on 22 I’d like to change my ssh port, provide me a solution please. ---

Put the edited files back to how they were before you funked with them first. Since using Virtualmin, manually editing files is last resort for me. Webmin, Servers, SSH Server, Networking, Listen on port - change to whatever. Then the firewall. Webmin, Networking, Firewalld, Add allowed port and add the new SSH port. Once you verify that it’s working, delete the Service ssh (22) from Firewalld. Good luck. [Next page](https://forum.virtualmin.com/t/cannot-find-linux-firewall/121532.md?page=2)
