my WRT54GL
Running tomato on it, and it is fantastic.
A friend of mine has had NAT type issues and internet problems in general for a LONG time. He had tried 2 routers before and had horrible luck with both. Did all the things tech guys ran him through.. port forwarding, static IPs, etc..
Well he bought a WRT54GL and I flashed it to tomato yesterday, set up a couple things and fixed his NAT type problems and had his router running securely in under 20 minutes. One of the best routers ever.
