Network Address Translation
Network address translation (NAT) is a methodology of modifying network address information
in Internet Protocol (IP) datagram packet headers while they are in transit across a traffic
routing device for the purpose of remapping one IP address space into another.
NAT Traversal
NAT Traversal is a general term for techniques that establish and maintain Internet protocol
connections traversing network address translation (NAT) gateways, which break end-to-end
connectivity. Intercepting and modifying traffic can only be performed transparently in the
absence of secure encryption and authentication
STUN (Simple Traversal of UDP over NATs)
STUN (Session Traversal Utilities for NAT) is a standardized set of methods and a network
protocol to allow an end host to discover its public IP address if it is located behind a NAT. It is
used to permit NAT traversal for applications of real-time voice, video, messaging, and other
interactive IP communications.
Procedure
NAT traversal and STUN server can be configured using the configuration files or locally.
