I found it weird that IPv6 folks are so against NAT as a cultural thing when it works perfectly well on IPv6. They're not fundamentally opposed.

I could have all of my servers in public subnets and give them all public IP addresses, but I still prefer to put everything I can in private. Not only does the firewall not allow traffic in, but you can't even route to them. It now becomes really hard to accidentally grant more access than you intended.

I would hazard that most devices on there internet are in the boat of want to talk to the internet but not be reachable on it.

Yea IPv6 folks are indeed against NAT philosophically because it's considered one of the big mistakes of IPv4.

There is a distinction between being publicly addressable and publicly routable. You can have the former without having the latter.

If you want more private addresses, IPv6 has a solution too: use ULAs and not GUAs. Design your internal network so it has mostly ULAs for application servers, database servers and the like, except for the reverse proxy having both publicly accessible GUAs as well as ULAs for talking to the rest of the network.

I personally use ULAs and GUAs concurrently on my network, because I have a residential ISP where my GUA prefix is not fixed.

I'm not opposed to anyone voluntarily using a NAT at all. I just hate it when somebody makes that decision for me, and that unfortunately still happens all the time.

If it's a well-reasoned decision, sure, but I do suspect that more often than not it's a lack of knowledge about alternatives that makes people still opt for NATs, and that just makes me sad on top of being annoyed with the inconvenience of having to tunnel when a direct connection seems so close at hand.

> I would hazard that most devices on there internet are in the boat of want to talk to the internet but not be reachable on it.

I highly doubt that. One big example is VoIP: Incredibly common these days, yet so much of it is going through centralized relays, and often for absolutely no technical reason.

How do you feel about NPT?

For a personal network where you decide to use NAT on ipv6? Sure, go ahead.

Being forced into a CGNAT on ipv6 is just a dick move though. And I believe that's the kinda NAT that has coloured the opinions of most NAT for ipv6 detractors.
