I went to and got a free dynamic dns account.
I then setup my ADSL router to use Virtual Server and port forward any incoming requests on port 80 to point back to my WAMP installation.
My router also had a configuration for Dynamic DNS - and it supports .
I have a Billion Bipac 7300.
In short that's it. My problem, as it turned out, was never with the dynamic DNS, but with some html redirect
