I have a broadband connection and have been trying to do this for a while. I wanted to setup a URL that could link to my system at my home at \”no extra cost\”.

This is link for phpMan on my system so might not be available at all times, but will try to keep it up and running all the time. I have fixed most of the issues with my system wrt hardware and have been running it for 4 days without re-start before trying this. So do comment if you like it. Will soon write on how I did this.
