Windows Remote Desktop via Internet

To setup my home Windows dev box to be accessible from outside I followed two main steps:

•  Configure my router to forward the remote desktop port.
•  Setup a free dynamic DNS service.

Last time I had to do this there was a service named dynamicdns.org which seems to still exist but no longer appears to be free. Instead I used dnsdynamic.org which is free and has a web API as well as links to and instructions for setting up native tools to dynamically update my IP address.
