I posted last week about not getting IPv6 on my Quantum Fiber connection. I haven't resolved that -- but I've got an even greater 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. Reading online, some say that Century Link uses VLAN tagging, and that may be my problem. Can anybody confirm this -- and what VLAN ID they are using? Can anybody confirm they are receiving inbound TCP via Quantum Fiber or Century Link?
