Have you read through the instructions for configuring the audio through a firewall? (http://docs.bigbluebutton.org/1.1/install.html#configuring-bigbluebutton-behind-a-firewall).

You will also need to follow the dummy NIC steps I believe, but do that once you start seeing a 1007 error related to ICE negotiation failure.

Well, i followed all instructions to set up SSL and setup FreeSwitch behind a Firewall althought i find this inctructions confusing, about editing the same file twice
.
.
.
.
 

Next, edit /opt/freeswitch/conf/sip_profiles/external.xml and change

    <param name="rtp-ip" value="$${local_ip_v4}"/>
    <param name="sip-ip" value="$${local_ip_v4}"/>
    <param name="ext-rtp-ip" value="$${local_ip_v4}"/>
    <param name="ext-sip-ip" value="$${local_ip_v4}"/>

to

    <param name="rtp-ip" value="$${local_ip_v4}"/>
    <param name="sip-ip" value="$${local_ip_v4}"/>
    <param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
    <param name="ext-sip-ip" value="$${external_sip_ip}"/>

Next, edit /opt/freeswitch/conf/sip_profiles/external.xml and ensure the value for wss-binding uses the external IP address

<param name="wss-binding"  value="EXTERNAL_IP_ADDRESS:7443"/>

.
.
.
. 

I still have the 1002 WebRTC error, any other ideas?

The changes to sip_profiles/external.xml aren't changing the file twice. The first set of 4 lines is what it starts as and the second set of 4 lines is what it's changed to.

Also, for the "wss-binding" parameter make sure you put in your actual external IP address not just the literal string "EXTERNAL_IP_ADDRESS".

Yes, i put the actual external IP there. i was confused about the  /opt/freeswitch/conf/sip_profiles/external.xml appearing twice... the first two blocks of code, i get that it is before and after, but the 1-liner 
<param name="wss-binding"  value="EXTERNAL_IP_ADDRESS:7443"/> i had thath commented out. Now i have edited that but i still have the 1002 error.

:/

Is your external IP in /etc/bigbluebutton/nginx/sip.nginx? There's going to be a misconfiguration somewhere in either the external.xml profile, sip.nginx, or firewall port forwarding.

The other possibility is FreeSWITCH not being up at all. When the 1002 error pops up if you answer "no" you will fall back to Flash audio. Can you successfully join with that?

If i hit "no" and choose flash, the mic tests begin and then after hitting "continue" it dials the call and after a moment, the test begin again, its like its not making the call, if i hit cancel, i get the desktop sharing just fine, but with no audio/video.

From /opt/freeswitch/conf/sip_profiles/external.xml
...
<param name="wss-binding"  value="190.64.208.2:7443"/>
...
From /etc/bigbluebutton/nginx/sip.nginx
...
proxy_pass https://190.64.208.2:7443;
...
I have port forwardings to the server internal IP address 192.168.1.189 of ports 9123, 7443, 1935, and 16384-32767

It should work right?

This has me stumped. It seems like you have everything covered, but it still doesn't work. Maybe try looking in /var/log/nginx/error.log for something about the websocket failing. You should see errors about trying to access html5client/check, but you can ignore those.

Can someone check if these settings are correct? Still cannot make the WebRTC audio call...

Those port forward settings look fine. The only thing you could change would be to change them to use either TCP or UDP as required of them rather than both, but that shouldn't really affect it

Did you try looking in /var/log/nginx/error.log for something about the websocket failing? If you see a message in the log then you know that the request is at least getting that far.

I had a fast look and i did not find nothing useful. I'll do more tests and collect some useful logs and post here if its worth it. Thanks for the ok on the firewall settings.

This are logs for the Ubuntu VM hosting the BBB server. I have no error logs on the proxy server. For what i can see, the useful bits are in the first error log, i would appreciate some help with interpreting that.

I just had an epiphany. Your port forwarding is only rules for WAN to LAN, but the websocket goes from WAN over 443 to nginx and then nginx tries to make a connection back through the public address through 7443. I bet that second leg of the journey is what's failing because that is likely classified as LAN to LAN. Try adding a second definition for 7443 for LAN to LAN and see if that fixes it.

I added that rule you said to me, like this.


I still get this error in error.log. Note that 192.168.1.189 is the bbb server internal IP, 192.168.1.112 is the firewall internal IP that gets the 80 and 443 from outside, and 190.64.208.2 is the external IP, just to make clear that.

First error line when start loading the page.

The second and third lines are basically saying that 192.168.1.112 (client) tried to make a connection to https://190.64.208.2:7443/ws and it was rejected. I thought that allowing LAN to LAN would let it connect, but that doesn't seem to be the case. At this point I'm not really sure what kind of rule would cover that connection, but that is the issue that is causing the websocket to fail.
