I posted last week about not getting IPv6 on my Quantum Fiber

concern: I'm not receiving any inbound TCP connection requests.
(Again, I'm not using the default router. I'm using an OpnSense router
built with a Qutom mini-pc.)
My outbound TCP is working fine. My router is receiving and responding
to ICMP PING messages. But packet capture at the router WAN interface
shows incoming TCP connection request are never arriving.
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,
