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,
