libportfwd
Set up port fwds and find external IP: C++/CMake wrapper for miniupnpc and nat-pmp libs
libportfwd
A basic, lightweight c++ wrapper around miniupnp and nat-pmp libraries for setting up port fwds, detecting max up/downstream bandwidth, and finding out external IP address.
Designed to wrap up miniupnpc+natpmp libs into a static lib with a small API so other projects can easily setup port fwds without shipping extra libs/deps.
Should detect any upnp or nat-pmp router and automatically use the appropriate library under the hood.
Uses cmake to build needed bits of miniupnpc..
NB/TODO
I don't have a nat-pmp capable device (eg: airport express) so haven't implemented that bit yet. only supports upnp atm.
Usage
See the demo in main.cpp, but here's the jist:
Portfwd pf; pf.init(2000); // 2000 = ms to wait for response from router pf.add(1234); // port to fwd to you pf.remove(1234); // remove port fwding on exit
