The solution you came up with (using two unused addresses from Since FreeBSD doesn't provide NAT64 natively, maybe Tayga could fill that role? I have no experience with Tayga, though, and I don't know if it'd work with all IPv6 setups (like TunnelBroker).

Unbound is a validating, recursive, caching DNS resolver. If you make the WAN IPv6-only, you'll need to use an external NAT64 service because significant parts of the Internet are still IPv4-only. Stateless NAT64 and DNS64 support opnsense/core#167. General settings Warning.

NAT64 preserves access to these services by performing IPv6-to-IPv4 translation. This means all clients will lose IPv6 connectivity eventually. 209. Just like Network Address Translation (NAT) can translate WAN to LAN addresses, NAT64 can translate IPv6 to IPv4 addresses. Devices on my LAN get assigned a local IPv4 via DHCP and can reach the management interface fine. Currently you have to manually add routes and addresses to the tayga tun Since NAT64 support is now coming (#167, opnsense/plugins#16), we also need DNS64.
