  Description     : A minimal, user-space, stateless NAT64, CLAT and SIIT implementation for Linux

Stateless IP/ICMP translation (SIIT), Stateful NAT64 and [CLAT]
are important mechnisms to pave the way to an IPv6-only future. I've
found the tools we currently have in Debian to provide and use these
services, Tayga and Jool, lacking in various respects.

Tayga has major performance problems due to being single-threaded and
comes nowhere near to even measily 100Mbit forwarding on modern
hardware but it currently is the only viable way to implement [CLAT]
on Debian.

[CLAT]: Is the client-side of a 464XLAT setup. This is used to support
applications using IPv4 literals on top of an IPv6-only access network.

Jool being an out-of-tree kernel module has to employ various kernel
hacks to get it's job done that lead to all kinds of jankyness. It's
reasonably fast though, so it's more suited for deployment as a
network service. Unfortunately the upstream project is in "maintanance
only" mode so my concern is it may get abandoned at some point.

Hence we need more alternatives for these services in Debian.

tundra-nat64 is a new userspace implementation of SIIT, NAT64 and
[CLAT]. It's multithreaded as opposed to tayga so my hope is the
performance will be much better.

I plan on maintaining tuntra-nat64 myself but I do need a sponsor :)

Thanks,
