I don't know if you still need help, but, First, I wanted to say that I was going to bridge the connections on my system, I found several posts saying basically "Shame on you, bridges are bad" and after researching, yes, bridges are bad. They are forcing software to act like a switch, which will never work as well as a switch. What most people DON'T tell you, ( I think they expect you to work out) is that the only thing stopping your other networks (subnets) from communicating is the firewall rules (or lack thereof) for that interface, I duplicated the default "Lan to any" rule on my second network, because I wanted that network to be able to communicate, and it worked fine, it does mean doing every firewall rule twice, but it works! So consider doing this.
If you want to be a bridge troll (kidding) them I do have one question. PFsense filters traffic in the interfaces that are bridge members by default, NOT in the bridge itself, you can change this behavior, if you edit some lines in system tunables. Here is the quote from pfsense docs
By default, traffic is filtered on the member interfaces and not on the bridge interface itself. This behavior may be changed by toggling the values of net.link.bridge.pfil_member and net.link.bridge.pfil_bridge under System > Advanced on the System Tunables tab
Has this been done?
