STUN issues with Ekiga 4.0.1 and RENAVISIO ?

Hi all,

One of my colleague is having issues with his Ekiga setup.

We are running the same version of Ekiga (4.0.1) on similar machines
(Ubuntu 14.04 x86-64). The only difference is that he's using KDE,
while I'm using Unity.

We are on the same physical network, with ports range already opened
for Ekiga.

While I can dial in the SIP number of a RENAVISIO conference and reach
the bridge without any problem (as I told you before in a previous
e-mail), it just doesn't work on his side... He still get the same
error message about Ekiga not being able to configure the network
automatically...

Here is an excerpt of his logfile (ekiga -d 4), where one could see
some STUN related errors:

What are we doing wrong ?

Any help would be greatly appreciated :)

Do you have this message too (on Unity machine)?

The above two errors mean that on his machine there is surely a firewall
which blocks packets to/from STUN server.  You could check this with
wireshark for instance, look at STUN lines.  Are you sure there is no
such firewall?

Hi Eugen,

No, I don't have the same error message on my machine. I used to have
it though, but that was before we configured our network to fit
Ekiga's requirements.

And I don't know whether there's a firewall installed on his computer.
I'll check that ASAP using Wireshark :)

Cheers, and thanks for your help !

Sam
