NAT certainly exists in IPV6, I use it on my home network for my nginx proxy VM. I cannot, for the life of me, figure out how to change the IP on the host so I do NAT on my router. 🤷♂️
Comment on CGNAT blocking external access to NAS. Looking to address this plus more.

Ipv6
Cgnats don’t exist in ipv6. Nat doesn’t exist in ipv6
What also could happen is your isp blocking some ports from outside its network as a security approach, but normally you can ask to free a range of port from the firewall.

This is not the Nat functionality as people associated with ipv4, and certainly it is not showing the drawback of allowing the communication only when the NATed client started the communication.
Even if they are alike they are not the same.
I reaffirm myself here. It is possible to have full ipv6 communication and providers do not have cgnats. It is your easiest and most uncomplicated solution with almost nothing to install to make it work.
And in addition, I have to say that I don’t see any benefit in using such functionality at home. If someone can illustrate me a use case I would be thankful

I use NAT on IPv6 so that I control which IP address is exposed. I’ve got /60 and all of my home devices are assigned unique IPs. What I like to do is set up a V6 address that uses the same numbers as my static V4 address and NAT that to my NGINX box, basically using the router assigned V6 as a “local” address.

Take wiht a bit (or a lot) of salt what I am gonna say. Because undoubtedly I am. Missing something here.
But if what you a already say is true probably you are not restricting anything. The recommended way to do so is with a firewall rule (probably in your router).
You are extending the subnet definition beyond the 16 bits. This can create problems and I doubt that your router will block anything if something crafted is received from Internet.
But of course, being the extremely big address space your are probably safe.
I any case, with a firewall rule in your router allowing only the proxy to go receive connections, you should be good and more standard conform

My ISP doesn’t support IPv6.

Honestly, I cannt believe it.
Double or triple check it. The problem these days is to get a semifucntianl ipv4, they are expensive, scarce and full of problems.
Ipv6 on the contrary is abundant and all enterprise equipment fully support it since decades.

I can totally believe it. Here in the Netherlands we still have providers that haven’t implemented IPv6. We’ve had one (Delta) finally starting their IPv6 rollout to fiber customers this year, not sure if they already finished it. Some providers are just slow AF unfortunately.

Truly incredible, shame on the.
Question then.
Are you experimenting some kind of connections problems?
I ask because I know some multiplayer games make a heavy use of the ipv6. Steam have some servers that are not reachable via ipv4, and don’t speak about vps…

My isp doesn’t support ipv6 in my area (Verizon). They claim to be in the process of rolling it out, but it’s been years that they have been saying that, so idk. At least they don’t use CGNAT, so it isn’t a huge deal for me after I set up dynamic DNS.

CGNAT but no IPv6? Despicable

It’s Mexico. The ISPs incredibly worthless and corrupt
