I'm new to SSH and Linux so please don't laugh if this is a simple question. I've looked and haven't really found anything using Google that does exactly what I want it to do.
Setup
Home LAN
Router - Listening for Port 443 - Redirects anything on port 443 to Port 22 on "sshserver"
Ubuntu Server (Behind Router) - name = sshserver - openSSH installed. Ip address 192.168.2.2 - SSH listening on port 22 - System-Preferences-Remote Desktop - Enable - Password - (Uncheck confirm each connection to this computer)
Outside my house
Ubuntu Desktop (name = workstation) with Putty installed. Obviously my IP address is dependant on where ever I am.
What I Can do now
I can ssh into my "sshserver" no problems using "Workstation". Everything is working great. I am connecting my Ubuntu "workstation" to "sshserver" using Putty.
What I have tried
I am under the understanding that when you check off "remote desktop" in Ubuntu, VNC will run on port 5900. Because I know the session screen page works (I can always successfully log in with SSH) I just want to just edit the Putty - ssh - Tunnel section.
On this scren I have tried entering: source port: 5900 destination port: localhost:5092
The reason why I have done this is I have the intention of using Applications - Internet "remote desktop viewer" application. In it I tell it I want an VNC type connection and that I want to connect on "localhost:5092".
This fails miserably. I guess I am just not understanding exactly how the tunneling happens and how to correct this issue. If anyone could help me understand how this works using the tools I have listed I would be really thankful!
THanks in advance.
