Why isn't my Kurento kms6 install producing srflx candidates?

Question

I've got Kurento kms6 installed on Linux 14.04 box on the cloud, but I've had to open all my high numbered TCP ports to make it work across the internet (why it's not using UDP would be a different question I imagine). It's only generating host candidates, not stun candidates.

My /etc/kurento/modules/kurento/WebRtcEndpoint.conf.ini file has the following entries:

stunServerAddress=217.10.68.152
stunServerPort=10000

I've checked that this stun server actually worked using

  https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/

It produced the following results:

 0.169  Done

The kurento log has the following lines, indicating that it did see the stun server entries:

When I stage a call, here is a set of the outgoing candidates messages in the log:

Any ideas?

Use a different stun server, this seems that is not working. Be careful when using this test page, as it already includes a sun server. I tested your stun server removing the default one and I haven't receive any srflx candidates.

I was careful. My suspicion is that you didn't get any candidates because you didn't press the "Add Server button" to add your entry to the list of ice servers. Here is a link to two pics that demonstrate that ice candidates were generated with just that ice server. http://imgur.com/a/jhMwC – Eric Davies Dec 11 '16 at 19:51

Why isn't my Kurento kms6 install producing srflx candidates?
