I'm trying to set up a network bridge between the on-board network adapter and a network card I put in the PCI slot. Both adapters are recognized by slitaz, but I do not know how to bridge them. I am trying to use the computer as a server/router WAN in from the modem in one adapter, and out to LAN in the other, and visa versa. I've searched around the web for solutions, but I could not find one that works for me. From what I understood, there's a tool called bridge-utils. I got the impression that if the computer reboots for whatever reason, I would have to run bridge-utils manually again, but I didn't even bother looking that far because I couldn't make it run once from the command line successfully. There was some alternative that was supposed to automatically bridge the networks if I created a config file called /etc/network/interfaces but considering that the /etc/network folder did not even exist, I fail to see how that could have worked. I did try a little copy pasting action to no avail just in case though. Last but not least, someone here set up a network bridge by renaming an eth0 interface to br0 in the udev rulse and apparently magic happened and everything worked. However, when I tried to find more details, all I could find was "simply rename it". The problem is that I searched all the udev rule files, and not one of them has the pattern "eth0" in them, so I fail to see what I would be renaming, if there is nothing to rename. I also fail to see how renaming an interface ends up reconfiguring the way two interfaces act by default. If anyone could shed some light on the topic, I would greatly appreciate all the help I can get.
build-tools and /etc/network/inferfaces:
