That's what the ULA is for. You can do whatever you want with ULA and you don't need NAT to have that if you only use GUA for WAN comms.

- MrHamburger 2y agoYour device with ULA address either needs NAT66 to be able to talk outside or it is destined to talk only in LAN forever.
- cassianoleal 2y agoFor WAN comms you give it a GUA address as I mentioned. Most of my v6-enabled devices have at least 3 IPs: one link-local, one ULA and one GUA. Some have 5 IPs, some more.

- dfawcus 2y agoNah - NPTv6, as it plays nicer. See RFC 6296 and RFC 7157.
