Firewall Configuration for Zoom Rooms

Firewall Configuration for Zoom Rooms

Zoom Rooms iPad controllers are typically linked to a single WiFi network, but if your Zoom Rooms iOS controller and Zoom Rooms are not connecting with one another when logged in, 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)


Using Zoom Rooms of course requires that the Zoom Room computer has access to your respective calendaring service. For example, if you are using Outlook, Google Calendar, or Exchange, the Zoom Room computer is 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 Zoom Room’s address, then you will most likely need to change your proxy settings on your computer. There are a number of options available to you.

  • Make sure that you are entering the correct proxy settings on the Mac or PC that is connected to Zoom Room.
  • You can configure the proxy server so that it bypasses the Zoom Room device on the Mac or PC.
  • Make sure that there are no other firewalls, web filters, or proxy servers on your computer or network.

In the case that your Cisco/Meraki router does not permit “hairpin”, you can disable Client Isolation by referring to the Meraki documentation in order to allow the Zoom Rooms iPad controller to access Zoom Rooms.

The following url is to be added to your list of allowed network domains if you manage your Zoom Rooms with Zoom Device Management (ZDM). Your company network may include firewalls or proxy servers, so you must add this url to your list of allowed network domains to allow communication with the ZDM server:
