  * If it connects to the global Internet, then need some operation to add a new global prefix and ensure the address selection in the right form. Or just put a NAT.

Please don't propose NAT as a solution to this.

  *   NAT imposes substantial additional complexity on many applications, and breaks applications that do not implement that complexity.
  *   NAT is strongly discouraged by the IAB (RFC 5902 section 4.1).
  *   NAT provides no advantages compared to using ULA + GUA.
