Bridge an IPv6 Network Back to IPv4 using NAT64

I am using Hetzner dedicated with SolusIO on the default subnet for ipv6 networking. I have separate cloud server for master SolusIO install/access.

Connectivity on created VPS's works just fine to addresses with ipv6 support, but is not connecting to ipv4 only domains.

Is there a in-house guide/tips available on how to enable ipv4 connectivity out/in from slave VPS?
