Jitsi self-hosting behind NAT hair-pinning

[ei8fdb]

I'm trying out Jitsi on my Cloudron hosted at home (behind a Mikrotik that supports hairpinning).

Jitsi installs with no issues, but when clients connect (either from the internal network - where Jitsi server is hosted, or from the Internet) there is no audio or video. Chat messages are sent successfully.

Pastebin of logs is available here.

When I look at the logs, this stands out most:

Feb 13 14:06:30 java.lang.IllegalArgumentException: No socket found for 172.18.20.240:10000/udp->192.168.88.197:60990/udp

I'm guessing port 10000 tcp/udp needs to be configured in my NAT rules?
Thanks!

@ei8fdb Answering my own question - yes port 10,000 needs to be added to your NAT rules. I created rules for both UDP and TCP. (Unsure if this is necessary but...)

Indeed, like with other apps which show additional TCP or UDP ports during installation, those have to be forwarded if a router with its own firewall is in front of Cloudron.

Further I haven't found a way to make jitsi work with a different port than 10000. Although Cloudron will allow you to change this port, jitsi will not work on say port 10001. Just mentioning this in case someone tries.

Thanks @nebulon.

Apart from being able to use something common, 443/80/etc, I don't think it's an issue to have it on 10000.

I don't know the percentage of Cloudron users who are odd like me and want to self-host, but it might be helpful to add this to documentation. In case they don't get to the forums.

@ei8fdb did you get it working? I have had that port open since installation (I also self host) but mine has no audio or video either. Similar problem I have to audio calls through matrix... It all works fine on the same network but not if devices are on different networks and as far as I can tell the logs show everything working fine.

Hi @ericdrgn I was waiting to have the time to test this morning.

I have tested just now:

1. server (8GB memory & 30% CPU dedicated) on home internet IP
2. clientA (laptop, browser) on external WiFi network
3. clientB (mobile android device, jitsi client) on mobile network

I did have video, and audio from both clients.

If you try some calls and grep for the messages I got? You can see them in the paste link.

Lemme know if you want any more information/help.
