Feature Request: IPv6 NAT support

Sun Sep 23, 2018 4:42 pm

I searched in this forum (search.php?keywords=IPv6+NAT) and wondered if nobody asked for IPv6 NAT support.

One goal of IPv6 was to reinstate the end-to-end principle of the internet - without NAT.
But in fact there are still reasonable reasons for IPv6 NAT support. Of course a small SOHO or home network will drive without NAT. But in advanced architectures there are some needs to NAT - even with IPv6: handling with dynamic prefixes, virtualization platforms, load balancers, complex network infrastructure and more.

So I'd like to request the feature to use NAT with IPv6 like the linux kernel and other platforms can already do.

For the votaries of academic principles of network: Nobody will force you to use it. But in the real world, there are some meaningful applications for it. So please exempt me from discussions about the sense of IPv6 NAT. This discussion comes from the same sphere as for example the short-sighted people who forced the unix timestamp to be an 32 bit integer so that we will drive into several problems in a few years. Reasonable from the academic point but useless in the reality.

Nowadays, IPv6 perimeter firewalls at my customers' networks run on Linux due to the lack of IPv6 NAT (especially prefix translation) support in ROS.

multi homed system needs to be able to retain one physical IPv6 address and NAT to a backup system for clients

+1 (for my dual-homed setup)

Also IPv4 to IPv6 address-port-translation is needed (initiator of connection on v4-side). Many small devices (aka IoT) or legacy devices only have IPv4 stack, but carriers will only offer IPv6 addresses in the very near future.
