I have asked several vendors we deal with about the newer technologies

vendor suggested their device supports NAT46 and NAT64 so may support
464XLAT, but since it is incidental rather than an official feature, it
may not support the full CLAT requirements. I have been meaning to do
some tests but haven’t had a chance yet. It is also a higher price point
than our current CPEs.



I have spoken to people who have looked into options such as OpenWRT
(which supports several of these technolgoies), however the R&D and
ongoing support is a significant roadblock to overcome.


We looked into this somewhat intently ~6 months ago and had not much
luck from vendors. Barely on their radar if at all.

We used our own custom OpenWRT build on a few select, tested consumer
routers to do 464XLAT. In the end we went to dual-stack with CGN on
IPv4. I wrote up some documentation on how we did it on my blog, but in
the end I can't recommend the setup we used.

I would love RouterOS and (various mfgr) CPE support for 464XLAT, then I
would be ready to give it another shot.


It sounds like I am where you were 6 months ago. We've been looking at
NAT64, MAP-T, potentially 464XLAT, and then dual stack with CGN on the v4
side. What did you experience with the dual-stack/CGN approach that keeps
you from recommending it? Academically, that setup seems the least fraught
with problems among all of the options.
