Wow, this was a neat little feature I never knew existed until recently.
If you're connected to SSH to a remote server, you can tunnel through firewalls and access services via your remote computer using this method.
In the PuTTY configuration:
- Go to "Connection" > "SSH" > "Tunnels"
- For source port, enter in the port number you'd normally use on the remote machine (for instance 4680)
- Destination should be "localhost:4680".
- Click "Add"
- When you connect, run an instance of the remote service on port 4680.
- On your local computer, access "localhost:4680" and it should appear as if you were looking at it remotely.
YAY!
