 ### Which ports are mandatory to be open in your firewall/router?
 Only those (if you access the Mastercontainer Interface internally via port 8080):
 - `443/TCP` for the Apache container
+- `443/UDP` if you want to enable http3 for the Apache container
 - `3478/TCP` and `3478/UDP` for the Talk container
