Last night at the Bozeman LUG (Linux Users Group) I presented for the second time, this time on a comparison of routing systems. It specifically examined open source router software for use at 50+ person LAN events on campus. I ended up selecting pfSense, and have been happy with it ever since. If you're interested, the slides are linked below. Consider this a mini-review of DD-WRT, pfSense and Untangle from the perspective of some of the most demanding users on the planet: gamers at a LAN party.
