Simple UDP server to test UDP port forwarding on Routers
To use the client, you'll have to specify both a port number and an IPv4 Address.
node client.js -i 127.0.0.1 -p 50
To use the server, only a port number is needed as the server will bind to all host interfaces.
node app.js -p 50
The client must be run after the server has been initialized, and within a short 8000ms timeout. Current functionality is limited to one payload and one reply per run.
