Bug#1041858: ITP: tundra-nat64 -- A minimal, user-space, stateless NAT64, CLAT and SIIT implementation for Linux
noowner 1041858 thanks I've decided to focus on upstreaming a kernel based SIIT/NAT64 solution instead of packaging tundra. Initial packaging work is here if anyone wants to continue this anyhow: https://salsa.debian.org/dxld/tundra-nat64 Upstream issue asking for tagging release https://github.com/vitlabuda/tundra-nat64/issues/1 Patches: https://github.com/vitlabuda/tundra-nat64/pull/2 - adding a Makefile https://github.com/vitlabuda/tundra-nat64/pull/4 - hardening --Daniel signature.asc Description: PGP signature

You're just a smidge too late, I think me and Paul got this. First come first sponsored I guess? :) Thanks for the offer nonetheless, --Daniel PS: You can expect a crunchy new Tayga PMTU/fragmentation bug within the fortnight if I don't forget :P

Hi Paul, good to know there's other people in Debian that care about IPv6 :) On Mon, Jul 24, 2023 at 10:26:03AM -0400, Paul Tagliamonte wrote: > As a current jool user, I'm very interested in this project.

FYI: I have another ITP pending for VPP (fdio-vpp) -- a very, very, very fast userspace packet processor (DPDK based) which also has SIIT/NAT64 support, but not fully featured last I checked. Might be interesting to you too. I just never got around to actually deploying VPP in my test network since my use-case for 10/40G routing/NAT64 dissapated so I never finsihed the package. It's about to come back though so stay tuned :) Thanks, --Daniel

Package: wnpp Severity: wishlist Owner: Daniel Gröber X-Debbugs-Cc: debian-de...@lists.debian.org, d...@darkboxed.org Hi, * Package name: tundra-nat64 Upstream Contact: Vt Labuda * URL : https://github.com/vitlabuda/tundra-nat64 * License : BSD3 Programming Lang: C 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, --Daniel
