Firewall Configuration for Zoom Rooms

Last Updated:

If your Zoom Rooms iPad controller and Zoom Rooms are on the same WiFi network but are still unable to connect with each other upon logging in, please check the following on your WiFi router or firewall:

Protocol: TCP Port: 9090

ZR Controller to ZR

Protocol: TCP Port: 443

ZR Controller or Scheduler to Cloud

Protocol: UDP

Port: 3478, 3479, 8801 ZR to Cloud
Protocol: TCP Port: 8801, 8802, 443 ZR to Cloud
Protocol: TCP Port: 8888 Client to ZR (Direct Share)
Protocol: UDP Port: 8889

Client to ZR (Direct Share)

Note: If you are utilizing the calendar integration with your Zoom Rooms, the Zoom Room computer also needs access to the respective calendaring service, such as Outlook, Google Calendar, or Exchange, to be able to check for calendar events and display them as upcoming meetings. 

If your Zoom Rooms iPad controller reports that it is unable to connect to the address on Zoom Rooms, it is likely related to proxy settings. You can perform one of the following: 

  • Enter the correct proxy settings on the Zoom Room PC or Mac device.
  • Configure the proxy server to bypass the Zoom Room PC or Mac device. 
  • Check other firewalls, web filters, proxy servers on the desktop or network. 

If your Cisco/Meraki WiFi router does not permit "hairpinning" to allow the Zoom Rooms iPad controller to access Zoom Rooms, please see the Meraki documentation to disable Client Isolation. 

If you manage your Zoom Rooms with Zoom Device Management (ZDM) and your company network includes firewall or proxy servers, you will need to add this ZDM url to your allowed list of network domains to allow communication with the ZDM server:
