My situation: I have a public ipv6 and a local ipv4 at home. I tried hard to forward a port, but it looks like I'm into a NAT, behind another NAT (?). So I tried to reach my ipv6 address outside my LAN and I got success, so then I set a simple apache webserver on a raspberry pi (who has an ipv6 too) and expose it to different DNS providers: dioniso.ddns.net, dioniso.crabdancer.com and dioniso.dynv6.net.
So, I can access these websites only in PCs that have ipv6 or ipv4 with tunneling.
The thing is, how ipv4 could reach this website? Some topics are saying that I need a proxy to "translate" ipv6-ipv4. Is it really necessary? If yes, where can I found a provider to do that?
Could someone give me some tips here? I'm pretty lost.
