Hello,
I’m sorry, it’s not so clear to me… In my understanding, in IPv6 there should be no need for port forwarding, the only thing that would prevent an IPv6 address to be reachable would be port filtering (obviously what I try to ping is the IPv6 of my NAS, not the one of the Box!). If the router does not actively block the said IP, then it should be accessible. Or is there no way to prevent the Connect Box 3 from blocking incoming connections to all IPv6 addresses within the internal network? (for what I understood, the main problem should be that dual stack IPv4/IPv6 is not really nicely implemented by Sunrise, so although pure IPv6 connections should go through, IPv4 connections would be blocked, therefore the need to rely on CloudFlare to correctly relay the traffic IPv4 <-> IPv6). I’ve read on this forum that CloudFlare can do the bridging, but so far since I can not even ping my IPv6 address, there is nothing that can work..
I’m sorry if I totally misunderstood how Sunrise operates…
