Taking a look in the doc of jitsi, show almost ports used in the
environment. IMHO, is good too add the UDP ports. Isn't clear from where is
necessary the UDP ports 10000 ~ 10100.
Also isn't clear (for me) the STUN in this scheme. I ask about this because
I have lots of people with connection issues. So, I ask if is possible the
people have problems with signalling between them because can't access the
Google's STUN. Is Jicofo, JVB or the user web browsers that need to contact
the Google's STUN servers?
Since now, thanks in advance.
