Awesome. I was aware of the linksys routers there you can load custom firmware on it. I just didn't know it also added vlan functionality. That's pretty sweet.
Also, due to this thread, I now want to pick up an old Cisco 1721 or something similar for my home network. Once you get it programed, it's obviously very reliable.
Too bad they're so expensive, but instead of using the ENET card in the router to connect to the cable modem at home, you can just by a cable WIC card for the router which in theory replaces the need for a cable modem. LIke $300+ though for the card. The router only costs like $30-40 used. I think I'll just stick with my crappy cable modem for now.
