Ubuntu – ssh: connect to host theremotehost.com port 22: Connection refused

port-forwardingremote accessserverssh

So I am trying to get ssh working on my server. I can connect on my local network with the local ip address of the server perfectly fine. When I try to connect remotely (through a domain name that I set-up for the server, which I know works) I get this connection refused error:

ssh: connect to host bahhudson.mine.nu port 22: Connection refused

From the research I have done into the problem it looks like something is going wrong with my router. I have configured port-forwarding, but that's the only think I can think is causing the "Connection Refused" error… My router is a WRT120N and I have configured it for port-forwarding based on Portforward.com, which seems somewhat outdated since some of those images are not exactly like what my router settings look like, but I have tried multiple ways for setting the portforwarding up, and I know that forwarding for port 80 works because my server has HTTP access which is working…

Also VPN access was getting blocked in what I believe to be a similar way, so the solution to the SSH port 22 being blocked might also be similar to that of the VPN being blocked as well.

Any ideas?

Thanks!

Your ISP may block connections to port 22 (nothing you or your router can do about it). Just set SSHd to run on a different port, e.g. 2222.

In /etc/ssh/sshd_config, change Port 22 to Port 2222 and then sudo service ssh restart. Port forward 2222 (or whatever), and try again.
