The GitHub README says the repository was initialized from libnatpmp-20120821 and records Thomas Bernard's 2007-2009 copyright. The protocol context comes from RFC 6886: NAT-PMP automated NAT port mappings, was implemented in Apple products from 2005 onward, and was superseded in 2013 by Port Control Protocol while retaining a compatible packet-format lineage. ### Adoption history libnatpmp's adoption follows the MiniUPnP ecosystem and peer-to-peer networking use cases where software wants an explicit router port mapping without relying on UPnP IGD. The MiniUPnP documentation includes examples for simple redirection and a P2P-style initialization state machine. In package managers, libnatpmp is small but useful: it gives applications a portable asynchronous NAT-PMP client library and gives users the natpmpc tool for testing gateway support. ### How it is used Applications initialize a natpmp_t object, send address or port-mapping requests, wait with select using the timeout helper, and read responses or retry. The API is intentionally event-loop-friendly because calls are asynchronous and based on non-blocking sockets. ### Why package nerds care Package nerds care about libnatpmp because it is the tiny sharp tool beside MiniUPnP: one library, one protocol, one CLI, and enough C API to let network applications punch a NAT mapping when the gateway supports NAT-PMP. ### Timeline - 2005: RFC 6886 later records NAT-PMP implementation in Apple products from this year onward. - 2007-2009: libnatpmp source records Thomas Bernard's copyright range. - 2012-08-21: The GitHub README says the repository was initialized from libnatpmp-20120821. - 2013-04: RFC 6886 documents NAT-PMP and says PCP superseded it in 2013. - 2020s: The library remains packaged as the MiniUPnP NAT-PMP client implementation. ### Related projects - libnatpmp is related to MiniUPnP and MiniUPnPd, UPnP IGD, Apple's Bonjour-era NAT-PMP deployments, and the IETF Port Control Protocol that superseded NAT-PMP. ### Sources -
