To see if there is any filtering going on, you need to do packet capture
at the OpnSense box:
https://docs.opnsense.org/manual/diagnostics_interfaces.html#packet-capture
and see if the packets arrive.
If they don't, then something upstream is filtering them. If they arrive
on the OpnSense WAN interface, then look at the LAN interface and see if
they are being forwarded appropriately by OpnSense.
I don't have any experience with OpnSense,
