Chapter 9 Topology Hiding

No NAPT Pinholes

•A hairpin of two pinholes in which both external terminations are provisioned with the NAT latching instruction cannot latch and cannot forward media. No NAPT pinholes are not allowed to (re)latch to the remote addresses on both sides.

•IPv6 hairpinning are supported on UDP and TCP.

•Coupling of Single NAPT pinholes is not supported.
