- QtNat is a lightweight C++ library built with Qt 6 for simplifying NAT port mapping using UPnP.
- It automatically communicates with compatible routers to create port forwarding rules, useful for peer-to-peer applications, multiplayer games, and remote access tools.
- Provides a simplified API for discovery and mapping, tested on local devices.
- Example usage includes creating an UpnpNat object, connecting to status changes, and handling different NAT statuses like NAT_FOUND, NAT_READY, NAT_ADD, and NAT_ERROR.
- Technical details include sending M-SEARCH requests for discovery, requesting and parsing description files, and sending port mapping requests using SOAP.
- Encourages testing on different devices and welcomes feedback via GitHub.
