[afnog] XLAT646 deployment

Sun Jul 4 21:24:43 UTC 2021

Actually, most of the cellular operators use 464XLAT, as there is no other choice in cellular.

T-Mobile also offers cellular broadband using CPEs with CLAT.

The problem of the CPE vendors, for wireline, is that they don't want to provide updated firmware, they want to sell you a new CPE, which makes sense because you will get Gigabit ports, WiFi6, etc., etc. The good news is that they will provide new CPEs with low volume, even just for a few thousands per year.

I've used cheap product for less than 15USD purchased in China with a custom OpenWRT.

OpenWRT supports the CLAT natively, but you can also use Jool (Open Source as well) for the CLAT, same as for the PLAT.

    Assume you mean 464XLAT, yes?

    Globally, T-Mobile in the U.S. have had large success deploying this 
    across their mobile customers. One of the largest-scale 464XLAT 
    deployments that has been documented.

    The main challenge you will get in the fixed-line world is CLAT support.

    I'm not sure of any source of truth that does a deep-dive on all major 
    and unknown CPE vendors that have CLAT support. Last time I checked, 
    outside of Android, iOS and Windows, it wasn't that great.

    Not sure how well it works as I don't run Linux.

    On the PLAT side, all major router vendors have decent support, 
    especially if they already had NAT64/DNS64 experience.

    Someone with more clue can chime in.

    Mark.
