Linksys Router No Longer Open Source
This link is mostly for my reference, but some of my geek readers might find it interesting.
I've recommended for several people the Linksys WRT54G router. It's a good router, and, up until v. 5 of the router, used open-source firmware so a lot of great hacks were out there to make the thing a full-fledged firewall solution.
Unfortunately, with version 5 of the router came a firmware from another company that is not open-source, so none of the firewall hacks mentioned in the link above work.
So when you buy one of these routers, make sure it's either a version 4 (or less) version of the above WRT54G router, or buy their new WRT54GL version of the router which uses the open-source firmware.
