What Is Stun Protocol? |
|
Answer» The Simple Traversal of UDP through NATs (STUN) protocol ALLOWS a client to discover the presence and type of NATs between the client and the public Internet. In addition, a client can discover the MAPPING between the private IP address and PORT number and the public IP address and port number. Typically, a service PROVIDER will OPERATE a STUN server in the public Internet, with STUN clients being embedded in end-devices, which are possibly behind a NAT.
