Yep. However, if you do that, you will need something acting as the gateway. If your host is going to be the gateway, it will need an address set in ifcfg-br0 and packet forwarding turned on. If eth1 and br0 are both in the same [public] network, you should just set the public IP address on br0 and add both eth0 and eth1 to the bridge and turn on STP. (I don't see why you need eth0 in this mix at all if you are just using it for guests on the local machine.) -- Christopher G. Stach II http://ldsys.net/~cgs/
