It classified NAT implementations as full-cone NAT, (address) restricted-cone NAT, port-restricted cone NAT or symmetric NAT, and proposed a methodology for testing a device accordingly. However, these procedures have since been deprecated from standards status, as the methods are inadequate to correctly assess many devices.
STUN works with three types of NAT: full cone NAT, restricted cone NAT, and port restricted cone NAT. In the cases of restricted cone or port restricted cone NATs, the client must send out a packet to the endpoint before the NAT will allow packets from the endpoint through to the client. STUN does not work with symmetric NAT (also known as bi ...
Various NAT traversal techniques have been developed: NAT Port Mapping Protocol (NAT-PMP) is a protocol introduced by Apple as an alternative to IGDP. Port Control Protocol (PCP) is a successor of NAT-PMP. UPnP Internet Gateway Device Protocol (UPnP IGD) is supported by many small NAT gateways in home or small office settings. It allows a ...

In computer security, a DMZ or demilitarized zone (sometimes referred to as a perimeter network or screened subnet) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to an untrusted, usually larger, network such as the Internet.
NAT is NOT what provides the security in this case, and, a stateful IPv6 firewall can easily have a default deny policy for incoming sessions without the breakage caused by NAT. NAT is unnecessary except for address shortages, or, extraordinary circumstances such as a desire/need to present a network as an artificially different prefix.
Teredo is not compatible with all NAT devices. Using the terminology of RFC 3489, it supports full cone, restricted, and port-restricted NAT devices, but does not support symmetric NATs. The Shipworm specification [6] original that led to the final Teredo protocol also supported symmetric NATs, but dropped that due to security concerns.
