My home ISP does CGNAT for IPv4, but provides native IPv6. I can use IPv6 just fine to access most of my resources, except for one specific server. I can access the server over IPv4 from my home network, and either over v4 or v6 from other networks I’ve tried. But I can’t access it over IPv6 from my home network.
What could be the problem here? Where do I begin to diagnose it
Yes, I can reach the IPv6 on the server from other networks. I don’t think it’s a firewall issue.
