I am having an issue with my zeroshell box. When I setup the bridge it works just fine; however, when it sets it up at boot it does not. I checking things with brctl after the boot and before shows nothing out of the ordinary. Removing the bridge in zeroshell makes things work very soon after and adding the bridge again its fine (until the next reboot).
Not sure if it matters but I am bridging an entire interface with a vlan interface.
