Absolutely dead-on!
IPCop is a good "Linux Router" solution, that you can download, throw on an old box, and then have it as your front-line of defence. It's versatile, and has FAR more options than any of the mainstream "routers" that you will find in stores. It's also extensible via add-on modules.
