An ethernet bridge ties together multiple ethernets to give the "illusion" that it is one ethernet. An interface that is added to the bridge is just a bridge port. The configuration for the NIC should simply add it to the bridge, e.g.: --- DEVICE=eth0 TYPE=ETHER BRIDGE=br0 ONBOOT=yes --- The resulting bridge device (br0) is the interface to the new ethernet. So, if you want to give it a static IP address, do it in the bridge configuration. A quick example: /etc/sysconfig/ifcfg-br0: --- DEVICE=br0 TYPE=Bridge BOOTPROTO=static BROADCAST=192.168.255.255 IPADDR=192.168.255.10 NETMASK=255.255.255.0 NETWORK=192.168.255.0 ONBOOT=yes USERCTL=yes IPV6INIT=no PEERDNS=no ONBOOT=yes --- Once that works, continue with the other stuff :). -- Daniel
