 ### Which ports does fairmeeting require?
 
-Media streams go with RTP UDP through ports 10000-20000. If your firewall is blocking those, as a fallback, https TCP 443 is being used (with poorer quality via a TURN server).
+Some organisations may have firewall restrictions. Media streams go with RTP UDP through port 10000. If your firewall is blocking those, as a fallback, https TCP 443 is being used (with poorer quality via a TURN server).
 
 On a terminal, you (or a technician at your office) can test if you can reach high UDP ports with the netcat command:
 
 ```
-nc -vuz fairmeeting.net 10000
+nc -vuz jvb-hetzner-0.fairmeeting.net  10000
 Connection to fairmeeting.net 10000 port [udp/*] succeeded!
