I'm having some difficulties at the moment with my Ubuntu SSH server. The only title I could come up with summarizing my situation was too long so here is my problem:
I recently discovered the firewall "ufw" command on Ubuntu, now I am trying to configure so that when I use putty to connection via SSH to my Ubuntu OS, that I could only use a very specific port number and not the default port "22".
For some reason, I am being refused access on my newly chosen port. Since I'm still new to Ubuntu and networking, I don't quite understand what's wrong, any advice?
