nat-mapmp

A NAT-PMP implementation with natmap.

Usage

  1. Download nat-mapmp. Add execute permission to it.

    # Download nat-mapmp
curl -Lo nat-mapmp.mjs $(
   curl -s https://api.github.com/repos/opportunityliu/nat-mapmp/releases/latest \
      | grep "browser_download_url.*mjs\"" \
      | cut -d : -f 2,3 \
      | tr -d \" )

chmod +x ./nat-mapmp.mjs

    ./nat-mapmp.mjs

    You can also use nohup to run it in background.

    nohup ./nat-mapmp.mjs &
