I've been switching the DSL manually for about a week now. I finally got a Linksys EtherFast� Cable/DSL Router with 4-Port Switch. I was planning on setting up a Linux box to do this, but this is all we really need. It can do port forwarding and filtering. It serves as a DHCP server for the local network. The installation is completely web driven so there is no platform depencence (there is a CD that comes with it that helps you set up your computer's IP settings, but I opted to use the Quick Start Guide instead).
Now, my dad and I can both be online at the same time. Someday, I may install Samba on my system and we will be able to share files and printers.
Next order of business: webcam.
