Verified with Zoom 7.1.5 — updated on July 12, 2026
Supported on: Microsoft Windows XP SP2 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Zoom Meetings\Zoom Meetings Settings Description
Default policy is empty. If this policy is a valid port range address, the client will use this range to set up listen sockets for connection requests between Mesh parents and children nodes. The nodes will also use this range to send signals and media data. If this policy is invalid or empty, the client will use "18801-19800" as the default port range. The format of this string should be "port-port", for example: "18801-19800". For Zoom Mesh Windows Firewall rules, the configured range must start at port 2000 or higher and span fewer than 5120 ports; otherwise, the firewall rule will not be added. If this policy is not set, client will use the default setting.
