Due to the subnet range 172.17.0.0/16 being utilized by Docker as its default bridge network, it is recommended that devices running the Zoom client not be placed on that IP range.
To allow connections between the Zoom Node management server, Zoom, and Node modules, the following firewall rules need to be added to your network.
