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.
