UPnP IGD implementation

Enable Moonlight streaming from your PC over the Internet with no configuration required

"TCMPortMapper.framework" is a clean and nice Objective-C API to provide knowledge about and improve the reachability of your machine from the big bad internet. "Port Map.app" is a nice standalone sample app using the framework to display reachability and enable setup of Port Mappings if your router allows for it.

qbPortWeaver is a Windows tray app that syncs the listening port of your peer-to-peer client (qBittorrent, Transmission, Deluge, or Nicotine+) with the port assigned by your VPN provider (ProtonVPN, PIA, or any NAT-PMP capable gateway) and optionally imports media files into Plex-compatible library folders using TMDB metadata.

Keep qBittorrent and OPNsense synchronized with a forwarded port from ProtonVPN or Gluetun.

A library providing a pure Rust implementation of a client for both the NAT Port Mapping Protocol (NAT-PMP) and the Port Control Protocol (PCP).

NAT-PMP gateway daemon & client

Multi-protocol Port Mapping for Node.js

macOS CLI to print public & local IP and DNS information, geolocation, address, map links, and share the information via Messages or Mail

A simple implementation of the UPnP protocol. Add port mappings for devices behind NAT.

Bidirectional STUN + UDP hole punching between two machines behind NAT — one C++ file per platform, one build command, no TURN relay and no dependencies. Proof of concept with disconnect detection.

nat port mapping library

Crystal library implementation of RFC 6886 (NAT-PMP), client side.

A qBittorrent NAT-PMP settings sync tool to update announce_ip and announce_port for clients behind a port-forwarded NAT routed through a Wireguard/OpenVPN VPN tunnel with a VPN provider that supports NAT-PMP for shared external IP address at the tunnel provider.
