Set network port range for Zoom Mesh parent-child node communication
Zoom 5.17.5
Supported on: Microsoft Windows XP SP2 or later
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". If this policy is not set, client will use the default setting.
Registry
HKLM
Software\Policies\Zoom\Zoom Meetings\Meetings REG Builder
BETAConfigure the state and elements to generate .reg, PowerShell, Intune, and SCCM outputs.
These exports replicate the policy's registry effect. Editing the registry directly is not the same as applying the GPO through the management console (no gpupdate, no central reporting). Test before production; HKLM changes require administrator rights.
