maybe someone can help me:
The reachability test of the next box fails despite having configured the router (a fritzBox) (hopefully) correctly:
port forwarding on ports 80 and 443 is active, the domain (example.dedyn.io) is whitelisted for the DNS-Rebind protection, IA_PD and IA_NA is enabled.
Even if it doesn’t matter: the isp is providing a full dual stack IPv4/IPv6 and the router is configured to default to IPv6.
The dyndns is also working correctly: the Box is reachable from external devices via the designated URL - as well as by the globla IPv4 adress of the router and the IPv6 adress of the NextBox.
What am I missing? Thanks a lot in advance.
(As I see it, this problem doesn’t cause any usability problems yet, but it’s still bothering me )
