Exposing big UDP ports range

[vladimir.d]

Is it possible to expose 10K or 20K UDP ports by one directive in Cloudronmanifest?

@vladimir-d I do not thing there is, but it should not be too hard to implement on the platform side. What's your usecase for this?

@mehdi It's needed with Screensy: https://forum.cloudron.io/topic/5480/screensy-simple-alternative-to-teamviewer-anydesk-etc?_=1641389991009

We have it running nicely on our instance. If we get that done, then we can submit it for the App Store.

@marcusquinn looking at the readme of screensy the udp ports are required for the turn server:

PORTS
-----

The following ports need to be accessible by the client for screensy to work.

+-------------+----------+-----------+
| Port number | Protocol | Service   |
+-------------+----------+-----------+
| 80          | TCP      | HTTP      |
| 443         | TCP      | HTTPS     |
| 3478        | TCP/UDP  | STUN/TURN |
| 49152-65535 | UDP      | TURN      |
+-------------+----------+-----------+

A turn server however is already part of Cloudron, I would therefore recommend to use that one instead.

@fbartels Thanks, makes sense.

Right, just use the turn addon - https://docs.cloudron.io/packaging/addons/#turn
