Hacking La Fonera – part 1

FoneraI bought a small La Fonera router for €7,5 a couple of weeks ago, just for the fun of replacing the firmware and tinker with a personalised Linux kernel and filesystem. I also installed a brand new web interface on it.

In the attached file you can find the details on how I replaced the bootloaders configuration, the Linux kernel and the filesystem:

I’m still working on building an RS232 level converter module for the internal serial interface on the router, and I’m trying to figure out the iptables firewall configuration so I can do NAT translation of the LAN side when I set the router as a wireless client.

Just trying to get a feel for it, really. Afterwards I’m thinking of installing a build environment on my PC and I’ll try to build the OpenWRT kernel and filesystem myself. I’m not sure whether there is a cross-toolchain for this I can just download or whether I need to create one myself? Creating a cross-toolchain from scratch is a bit of a challenge, I’ve done it once before, but it does take a couple of days until you get all the versions right and get the thing to compile properly.
