NAT-PMP is short for NAT Port Mapping Protocol and is similar to UPnP but found more commonly on Apple devices and programs. A growing number of programs support both methods. pfSense® software supports both, and the service may be configured at Services > UPnP & NAT-PMP.
Just to avoid confusion - "NAT Port Mapping Protocol (NAT-PMP) is a protocol for establishing NAT & port forwarding automatically without user effort. WIth no NAT-PMP supported you just need to configure settings manually. For these protocols the port numbers are changed so that the combination of IP address and port information on the returned packet can be unambiguously mapped to the corresponding private network destination. RFC 2663 uses the term network address and port translation (NAPT) for this type of NAT. Aug 21, 2014 · Open.NAT is a lightweight and easy-to-use class library to do port forwarding in NAT devices (Network Address Translator) that support Universal Plug and Play (UPNP) and/or Port Mapping Protocol (PMP). It is written in C# and works for.NET and Mono. The command specifies that the NAT maps the destination port 80 of the Internet resource to the source application port 8080. The command specifies that the tenant compartment that has the ID TSQATenant contains the internal address and internal port. This example uses the placeholder a.b.c.0/24 to represent a public Internet address prefix.
The NAT Port Mapping Protocol (NAT-PMP) NAT-PMP is the direct concurrent to the UPnP IGD specification. It is providing a way to do NAT traversal. It is part of the Bonjour protocol specifications. You can get the description of this simple protocol here or by reading the draft. At the moment it is mainly supported by Apple software and hardware.
- Local Service Discovery (LSD), Distributed Hash Table (DHT), Universal Plug and Play (UPNP) and NAT Port Mapping Protocol (NAT-PMP) supported; - TP (Torrent Transport Protocol) and PeX (peer Network Address Translation-Port Mapping Protocol (NAT-PMP) is found only in Apple AirPort base stations released in 2003 or later.

The NAT Port Mapping Protocol (NAT-PMP) is a network protocol that is used for the automatic establishment of network address translation settings and port forwarding configurations, with no effort from the user. beSTORM specializes in testing the reliability of any hardware or software that uses this network protocol as well as ensuring the
Port mapping/opening ports isn't necessary for Acquisition to work, but it will improve it's performance and download speed. Automatic Configuration If your router supports the NAT Port Mapping Protocol (AirPort Express and AirPort Extreme) or UPNP (many non-Apple routers), Acquisition will automatically open the required ports when it starts up.
