[Firewall] Help configuring internal rules

I have two internal interface cards: br1 ( & br2 (

I want to have all access to the host firewall allowed for br1. For this I
added TRUSTED_IF="br1". Which worked fine until turned on br2 which I only
want to allow dhcp(upd/67) & dns(udp/53). I added LAN_OPEN_UDP="53 67" to
allow this but this basically disabled my TRUSTED_IF config since it now
appears to only allow 53 & 67 to access the firewall host. Can I do what I
want to do with the configs or do I need to add custom rules?
I also want to allow hosts on the br2 network to access certain ip hosts on
the br1 network such as the printer.

Any help on this would be appreciated.
