STUN stands for Simple Traversal of UDP[User Datagram Protocol] Through NAT[Network Address Translators]. It allows for computers behind a NAT router to host and provide UDP information without having to create rule exceptions on the router, or provide specific information to the NAT service. When specified within Tigase, XMPP and UDP communications can be directed to a specific STUN server which will then handle incoming requests to your network. You may use a public, or your own STUN server with Tigase.
