Not a clue what caused this... did a factory reset on OPNsense and started from scratch... working fine!  ??? ::)

Hi all,

Recently started playing around with Opnsense, and so far it's been great. I've got my existing Unraid box connected, running a reverse proxy, and a number of other docker services and VMs, one of which being Home Assistant.

All of the exposed docker containers on the reverse proxy are able to be accessed remotely without any firewall changes (beyond pointing traffic to the Unraid server on the appropriate port. It's only Home Assistant that will not connect as it's running on it's own VM.

Neither the Unraid server or the HA VM are on any VLANs and all using the default LAN. Using my old Asus router, with the same static IP and routing configs, HA and the other docker containers work without any issue.
It's just Opnsense that won't allow it.

My very high level network topology:

25.25.10.1 - Opnsense
25.25.10.200 - Unraid Server running the reverse proxy on port 80/443
25.25.10.250 - Home Assistant running on port 8123





I've tried adding rules in both the WAN and the LAN around allowing port 8123 but nothing I've tried so far has worked, but my understanding is that due to the fact they're all running on the LAN anyway, there shouldn't be anything blocking LAN <-> LAN communication?

Thanks in advance
