       STUN  Servers  are  used  to help clients behind NAT to tunnel incoming calls through. This server is the
       counterpart to help the client identify the NAT and have it open the proper ports for it

       If the IP addresses of your NIC are 10.0.1.150 and 10.0.1.151 the proper and default use would be:

       stund-h10.0.1.150-a10.0.1.151

       add -b option to detach the process

       stund-h10.0.1.150-a10.0.1.151-b
