VNC over SSH Tunnel in PuTTY
From Proxmox VE
Contents |
The Network Setup
Let us take a network setup wherein the VNC Server machine and two linux machines are on the same LAN and the controlling VNC Client (Windows Box) is on a remote network possibly behind a NAT and different subnet.
In an actual deployment scenario, the VNC Server and the two linux machines were Virtual machines on a remote Proxmox VE server. This was useful to configure the remote router from a browser in the machine with the VNC Server.
Example Network Parameters
All parameters have been chosen to be unique so that they can be identified in the screenshots here.
- VNC Server IP: 10.0.0.5
- VNC Server Port: 5900
- Forwarded VNC Server Port on localhost: 5903
- Linux Proxy Host: mydomain.dyndns.org
- Linux Proxy Host's SSH Port opened on the WAN: 22
- Linux Port Forwarding Host: 10.0.0.6
- Linux Port Forwarding Host's SSH Port opened on LAN only: 22
- Proxy Port: 3000
Client Software
On the Windows VNC client machine, we need to have the following installed:
