# Firewall

This page is mostly a placeholder for now, but configuration of the firewall
is -of course- very important.

First idea: the ports that need to be opened are:


| Port(s) / range | IP version | Protocol | Application            |
| :-------------: | :--------: | :------: | :--------------------- |
| 80, 443         | IPv4/IPv6  | TCP      | nginx, reverse proxy   |
| 8443            | IPv4/IPv6  | TCP      | nginx, federation      |
| 7881            | IPv4/IPv6  | TCP/UDP  | coturn/LiveKit TURN    |
| 3478            | IPv4       | UDP      | coturn/LiveKit TURN    |
| 5349            | IPv4       | TCP      | coturn/LiveKit TURN    |
| 50000-60000     | IPv4       | TCP/UDP  | coturn/LiveKit TURN    |


The ports necessary for TURN depend very much on the specific configuration
[coturn](../coturn#configuration) or [LiveKit](../element-call#livekit).
