NAT-PMP (NAT Port Mapping Protocol)

NAT-PMP (NAT Port Mapping Protocol) is a protocol that allows devices inside a private network to automatically request and set up temporary, secure pathways (port mappings) through a router to the internet. This enables applications like gaming, file sharing, or remote access to communicate effectively without manual configuration. Essentially, NAT-PMP simplifies and automates how devices open specific channels for incoming data, ensuring smooth and secure connectivity while maintaining the network's overall security by restricting unnecessary access.
