What are the differences between NAT types defined in RFC 3489 and RFC 5780? To understand the differences to be explained below, you must be familiar with the Mapping Behavior and Filtering Behavior of a NAT that we covered last time. What is STUN? STUN is a protocol that allows two devices (P2P devices) to discover the presence and types of a NAT between them, and to find out what Exte...
