My ISP (Unitymedia Germany) tunnels IPv4 traffic through slow and unstable CGNAT (they call it "AFTR", which seems to be a similar thing) but comes with reliable and native IPv6.
Now, is there any way I can take full advantage of the IPv6 connection and access IPv4 hosts through the native IPv6 connection from my Win7 PC?
Naturally, I have searched Google, but any hits are about accessing IPv6 through IPv4, which is the opposite of what I want to do. I've also come across buzzwords like NAT64 and DNS64, but couldn't find much information about it for end users.
If it helps, I have a linux server with IPv6 in a datacenter near me, which could be abused for any potential shenanigans.
This sounds like it works sort of in the same way as what my ISP is giving me. Will it be more reliable and yield better performance although it's a more public service? – Cobra_Fast – 2014-10-22T20:30:47.483
Probably not, unless your ISP's AFTR is really bad. Your ISP is giving you DS-Lite. You still have IPv4, but it is transported over IPv6 to your ISP's AFTR and NAT'ed there. With DNS64 you don't use IPv4 yourself at all anymore but pretend that the whole world is IPv6 and the NAT64 service provides access to the IPv4 internet. Either way there is NAT involved, the difference is in the details, and your ISP's equipment is closer to you than some service based in The Netherlands... – Sander Steffann – 2014-10-22T21:45:46.023
