[Users] Can We Use the Stun server for NAT supporting,

[Daniel-Constantin Mierla]

Hello,

stun is recommended when the client properly implements it and does not 
sit behind a symmetric NAT (like linux box). For these cases you need to 
use server side nat traversal, look at nathelper/rtpptoxy or 
mediaproxy/mediaproxy.

Cheers,
Daniel
