Because they're on different physical ethernet port

Your dom0 IP is on eth2 while the bridge is over eth0.
If the IP address in dom0 is at eth0, it should work. This is probably
the easiest one for you, by moving IP configuration from eth2 to eth0
(and possibly change some network cabling).

Another way to do it is create the bridge for eth2 instead of eth0
like what you have now.
