Nighthawk M5 MR5200 Ports

[Mindz]

Hi

For our phone app in the company I need to configure certain things (Firewall-Einstellungen (mitel.com)

Hosts

• *.mitel.io
• *.amazonaws.com
• *.bugsnag.com
• *.gstatic.com
• cdnjs.cloudflare.com
• *.chime.aws
• firebaseinstallations.googleapis.com
• fcmregistrations.googleapis.com
• api.ipify.org
• maps.googleapis.com
• login.microsoftonline.com
• 99.77.128.0/18

Ports

• 7443 – TLS
• 16384 – 32768 UDP (RTP/SRTP)
• ICMP
• 443 – TCP
• 3478 – UDP

Unfortunately, even though I have put port forwarding in place for my device's IP and the ports 

• 16384 UDP
• 32768 UDP
• 443 – TCP
• 3478 – UDP

it still won't work. I cannot select the port range 16384-32768, but would have to add them all manually. Also I don't see the option for port 7443 – TLS and ICMP. And where can I add the hosts as required by the link above?

Thank you
