For the past couple of days I’ve been playing with Ubuntu Server and transparent proxying. What fun!

If you, like me work for a business/organisation which offers free wireless internet to the public (or even if you leave your home network open) you would be wise to keep an eye on what visitors are using your internet connection for.

We will be setting up an Ubuntu box which intercepts all traffic going out to the net and redirects any destined for port 80 to a squid proxy. It logs the destination of the traffic before sending it on it’s way so you know what your internet connection is being used for.

Bring the Thunder…

First up set up a box with 2 network cards installed, install Ubuntu Server onto it, and assign the network cards with static IP address.
