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
3478, 5349 IPv4 TCP/UDP coturn, TURN
50000-60000 IPv4 UDP coturn, TURN

The ports necessary for TURN depend very much on the specific configuration of coturn.
