To configure IPv6 NPTv6 on Linux to allow more hosts behind Verizon Wireless LTE IPv6 single /64 prefix
View vzw-lte-ipv6-prefix-translation.md

Problem

Verizon Wireless assigns you ONE IPv4 address and ONE /64 IPv6 prefix for their cellular service, and VZW would reset your datalink once they received 1 packet with an illegal source address.

We have NAT for IP but for IPv6 we would like to avoid address translation to get some kind of end-to-end communication.

Solution

NPTv6, defined in RFC6296, would help us to do stateless prefix translation for IPv6.

Speak the IP address of your linux machine. Perfect for Raspberry PIs or other headless servers with audio output. Just plug in a speaker or earphones and wait to be told the IP address to ssh to!
