Hi,
I have just been setting up OPNsense 24.1-amd64 on a Fujitsu S920 with a Broadcom dual NIC card.
Install went OK and I have so far managed to setup the WAN with VLAN tagging for the ISP. I software bridged the two NIC's on the broadcom card and applied the ACCEPT ALL firewall rules to the bridge. So far I have still to see any traffic into the internet, but thats an issue which I am sure is relatively easily resolved.
The main problem I have encountered so far is that my HomeAssistant instance which is running on a Odroid Hardkernel N2+ is simply not accepted by the OPNsense firewall. It recognises the that the N2+ is plugged, the NIC lights are correct and flashing so there is a connection. However the DHCP never issues an IP address. However if I set a static lease in the DHCPv4 service with the MAC address - it populates the MAC and fills out the N2+ identity - which proves that the firewall recognises the NIC at least. Checking all the logs I can find - there is no mention of the Odroid asking for an IP and no obvious signs of the firewall dropping packets. DHCP is definately working on the firewall - its as if the the Homeassistance instance is been blacklisted in some way with no traffic been allowed in or out of it. I tried pinging the static IP address which I set and nothing gets through. I even tried using a USB based NIC on the Homeassistance board to try to eliminate the onboard NIC as the source of the problem and the behaviour is the same. I also attempted to setup the Homeassistant integration within homeassistant instance - but not surprisingly with no path between it and OPNsense it wouldn't recognise the Router and so failed. I also attempted to connect the Homeassistant to the router by an intermediary Mikrotic switch but same result.
If I pull out the Odroid and present it back onto my ISP's router its recognised immediately and just starts working.
This is going to be a deal breaker for me as without the Homeassistant its not a functional setup for me. I have trawled the internet for answers and have come across a few instances where others experienced similar issues with Homeassistant and OPNsense and no one ever came up with a working solution. Any ideas and where to look to resolve this.

Did you set the two mandatory tunables as instructed in the documentation?
Not to sound dumb but can you point me to the specific document. I set one mandatory tunable when bridging the two NIC's onto the LAN.
A snippet of information - the issue is not with the Odroid N2+ because I just plugged in another N2+ running Coreelec directly into the OPNsense router and it was detected immediately.
UPDATE:
Thanks for the heads up, I had missed the removing NICs from filters step and I have just gone and checked that. The good news is that this resolved my issue and Homeassistant is now on the network.
