It should be solvable by configuring.

I use bridge device br0, a remote dnsmasq server for DHCP and DNS. sysctl.conf is
configured so that br0 works as expected: passes DHCP requests thrue.

Your case is different than mine, so you need different configurations.

Googling examples is a good start.
You could try to use iptables LOG rules to track down problems.
