So know you know this will be pathetic, I'll begin…

Recently, I convinced my family to switch to a DSL service to replace our pathetic dial up “connection” and manage to save $10 per month in the process. Now the quick snappy connection is nice, but we needed to have more than one computer sitting next to the modem to be able to connect. The solution was a little donation from a friend of my mother's at her office’s IT group; a (still shrink wrapped) Linksys DSL/Cable router!

Anyway, I need to open up a few TCP and UDP ports on the built in firewall, however, after playing around in the browser interface, the only readily available features seem to by IP filtering, DHCP settings, etc. After a quick Google search, I found some vaguely relevant links, most of which touted the importance of “only keeping open the ports you need, for maximum security,” and other sermons you might deliver to an absolute beginner. So, sadly, I think this is knowledge I must be spoon fed, so perhaps someone has a pre-fab response for the occasions when someone asks something like this?
