History

Basing this post on the previous VNC over SSH article, I was thinking of a way to be slightly more secure while using Wireless Hot Spots (Internet Cafes for example), where someone with sniffing programs could be lifting your username, passwords and email that you read right from the wireless connection.

Ingredients

A proxy server running in your 'home' network
SSH server running on the same box (or on your home network for advanced users)
An open port in your firewall pointing to the SSH server (changing your SSH port is recommended for security)
Putty on your laptop (or remote PC)

Prerequisites

Setup your proxy server and record the port that it runs on. I'm using Squid proxy (port 3128)

Remote Laptop Steps

Open putty and connect to your home network SSH server
Add the tunnel for the proxy server (3128 for squid)
- See the previously mentioned article on this
Open IE or Firefox (or whatever)
- Add the following LAN Proxy settings: 127.0.0.1:3128

Enjoy surfing via your secure SSH tunnel!

Verify

To verify this is working, do the following:

Browse to www.whatismyip.com and note the IP
Perform the Remote Laptop Steps
Browse to www.whatismyip.com and note the IP

You should notice a DIFFERENT IP and you should recognize it as your home network's external IP.

Further applications

Reroute your email client through the tunnel
