We just went to replace the bridge/firewall services one one server with the same on another. It's pretty simple, and I literally cloned (w/ rsync) a third server that does this onto the one that will be the new one. Then copied the /etc/sysconfig/iptables from the one being replaced, and brought it up this morning.
Specifically what did you rsync? If you copied the ifcfg files, you probably need to adjust the HWADDR in each. If you didn't get all of /etc, you might need sysctl.conf. I'm guessing that's the case, given the symptoms and the fact that you had to also copy the iptables file.
ifcfg-eth0
DEVICE=eth0 BRIDGE=br3 BOOTPROTO=dhcp HWADDR=aa:bb:cc:dd:ee:ff ONBOOT=yes
There should not be a BOOTPROTO in this file.
ifcfg-br3
DEVICE=br3 ONBOOT=yes TYPE=Bridge BOOTPROTO=static IPADDR=<our ip> NETMASK=255.255.254.0 NETWORK=<our nw> GATEWAY=<our gw>
You don't need NETWORK here.
It would also be helpful to see the contents of /etc/sysctl.conf or the output of:
# cat /proc/sys/net/ipv4/ip_forward # cat /proc/sys/net/bridge/bridge-nf-call-* # brctl show
