Vadosity Router Tool

From Vadosity:

The Vadosity Router Tool automatically updates your Linksys router to reflect the location of your computer in a dynamic IP environment. That is, if you are running an application, playing on online game, or hosting a Web-server behind a router, then the Vadosity RouterTool tells the router where you are so you don't have to. You no longer need to manually update your router settings to reflect a changing IP address. Just set up the Vadosity Router Tool once, and it will automatically update your router whenever your computer's IP address changes.
