Debug pfSense firewall and network

I'm struggeling with fw rules in pfSense and needs help to find out how to solve. The case: I'm running pfSense in transpartent bridge with static public ip on the WAN interface. NAT is disabled like it always have and this is required for the bridge to work. The system has worked for years, something has happened that isn't clear to me. WAN, LAN1, OPT2, OPT3 are in the bridge. Somehow, the fw has started blocking traffic between local LAN1 and OPT-interfaces. And I can't find out why. It says that default rule stops it, but the default roule for all local interface + bridge is allow-all. When I click EasyRule on the blocked traffic, it just adds another local allow that is already there and doesn't help. The task may require more work on other network things, but for now I just want to solve this fast, today and now. Let me know if you really really can pfsense and can work now.
