You probably mean 464XLAT .... Ask you vendors. They should support it. Ask for RFC8585 support, even better. If they don't do, is because they are interested only in selling new boxes ... just something to think in the future about those vendors. I can tell you that many vendors now support or are waiting for some customers to ask for it, the CLAT. I've been doing this for many customers. Sometimes, they only do under request, same as many other firmware features.

When you give them Ethernet cable that has internet on it, whatever it gets plugged into must support CLAT in order for 646XLAT to work. I was not able to find any small devices that support it natively, at least according to their description. The only way I found to enable CLAT support is to flash those devices with OpenWRT, which is not really an option when you are giving away those tiny boxes to residential clients when they sign up with you. So for now we're stuck with CGNAT. :( I do hope I'm wrong and you can tell me which device works with 646XLAT out of the box. And hopefully it's something TRENDnet's. -- Roman V Tatarnikov https://linkedin.com/in/rtatarnikov W: 310 929 2607 | C: 805 746 2886 ********************************************** IPv4 is over Are you ready for the new Internet ? http://www.theipv6company.com The IPv6 Company This electronic message contains information which may be privileged or confidential.
