When an interface is part of the bridge, you must not try and use the interface directly. I.e once eth2 is part of br0, don't use eth2 again. Most importantly never assign an IP address to the interface. Many people doing this kind of thing end up reading the IP address of the interface (eth2), then removing all addresses from the interface (eth2) before assigning it to the bridge, then apply the IP address back to the bridge device. 2. The bridge device itself has a MAC address for local packets. This MAC address is based on all the devices in the bridge (by default). Therefore when eth2 is added to a bridge with other devices present, the MAC address for locally sent packets will change.
