I have a USB to ethernet device connected to CentOS 6.5 on my laptop.

I setup ifcfg-eth0 and added BRIDGE=br0 on eth0 did service network restart, all came up.

"seems" to be working.

However when I plug an ethernet device into the USB port that is wanting DHCP it is not getting an address.

Is there something I missed in the setup? I was expecting the device connected to the USB to be bridged to my same network and be able to get a DHCP address on the same network.

Thanks,

Did you set the interface to 'BOOTPROTO="none"' and the bridge to 'BOOTPROTO="dhcp"'? When you traditional bridging, the bridge takes the IP, not the interface.

Also, there is/was a bug where the bridge name has to sort alphabetically after the interface, so I got into the habit of using 'vbrX' as the bridge name.

If this doesn't help, please share you interface and bridge config files.
