22 | * This code is based on ministun.c, that is based on Asterisk old STUN code. | ||
23 | * This code provides some support for doing STUN transactions. | ||
24 | * The simplest request packet is just the header defined in | ||
25 | * struct stun_header, and from the response we may just look at | ||
26 | * one attribute, STUN_MAPPED_ADDRESS, that we find in the response. | ||
27 | * By doing more transactions with different server addresses we | ||
28 | * may determine more about the behaviour of the NAT boxes, of | ||
29 | * course - the details are in the RFC. | ||
30 | * | ||
31 | * All STUN packets start with a simple header made of a type, | ||
32 | * length (excluding the header) and a 16-byte random transaction id. | ||
33 | * Following the header we may have zero or more attributes, each | ||
34 | * structured as a type, length and a value (whose format depends | ||
35 | * on the type, but often contains addresses). | ||
36 | * Of course all fields are in network format. | ||
