[jitsi-users] ICE problem - university network


#1

Hi,
I'm a new user and I apologize if I'm rising a naive question.
For reasons that clearly I do not need to discuss in this list I'm
trying to force "my community" to abandon Skype and move to Jitsi. Now
I'm experimenting an "ICE failure" problem in connecting with some of my
colleagues working in a public University in Italy. If I understand
well form reading the list this is a quite common problem and it has to
do with the network "restriction policies" implemented at the
University level. I'm not an expert and my question is: is there a way
to configure Jitsi to work in such an environment without having the
possibility to modify the network policy of the University?

Thanks in advance for any help.

ICE failure basicly states that there was no way to connect you and
your partner.
First make shure that your firewall is configured correctly, as you
and your partner are in the same network (university) and should in
theory be able to communicate using your private IP adresses this
seems to be the most likely problem.
In case your University restricts network internal trafic and has as
strange nat: try finding a XMPP server which supports jinglenodes.

Thanks a lot Yannick.
Actually I'm in a different University and outside my colleague's
network. If I got your suggestion correctly I should ask my colleague
to setup Openfire with the jinglenodes plugin, configuring it as in

https://java.net/nonav/projects/jitsi/lists/users/archive/2012-08/message/75

and this should be able to solve our connection problem. Did I get it
correctly?
Thanks again for your help, I'm really looking forward to dismiss Skype.

Yes, this should work.

Yes, this should work.

Apparently to have Openfire up and to be able to exploit jingle-nodes
plugin you need

Installation
Make sure Openfire is running on a Public IP interface and with
Firewall opened for UDP Traffic both ways on port range 30000 to 50000.

This does not seem to solve the "behind the wall" issue. I'm surely
missing something basic, sorry to have bothered you. Thanks again for
your attempt to help me.
