I'm new to this stuff, but I am trying to set up an ssh server in Ubuntu. I am able to log in locally to the server, but when I am off the network, I get "port 22: Connection Refused".
Having spent a long time reading forums and configuring things, I have come to believe that it is because I have not performed any port forwarding. Is this necessary even though I ONLY have a modem with one ethernet cable out to my one computer on this network? If so, what will port forwarding do that isn't already going on? Furthermore, is port forwarding even possible using a dynamic ip address (which I have)?
Thank you! -Matt
