Now to go back to the bridge theme - where is the best place to set the 0.0.0.0 IP addresses ? In the network config, or should I leave that all in place and just reconfigure everything in rc.local ?
Do the 'brctl' setting endure across boot sessions, or does the bridge need defining and setting up at every boot or network restart ?
Have a look at the Fedora examples at http://www.shorewall.net/bridge.html (about halfway down the page) for ifcfg-br0 and ifcfg-eth*
