First thing to check is if our Orbi does still get a public routable IPv4 address assigned. More and more ISPs are no longer associating these addresses to consumer connections. Much more they tend to change parts of their infrastructure towards Carrier-grade NAT - without letting the customers know. Just looking at the dynamic DNS and use whatever tool or site to check for open ports alone isn't sufficient.
- Not sure of exactly what the public IPv4 number is but would it begin with 108.XX.XX.XX?
If so, yes I have that address.- This 108.x.x.x address is the one you have got assigned in your router WAN resp. Internet port, or the one your DDNS does point to for the NAT connection? 100.64.0.0 to 100.127.255.255 would be the typical CGN address range.
