Additional vCenter Server TCP and UDP Ports
vCenter Server is accessed through predetermined TCP and UDP ports. If you manage network
components from outside a firewall, you might be required to reconfigure the firewall to allow access on
the appropriate ports.
Required Ports for vCenter Server and Platform Services Controller lists ports that are opened by the
installer as part of a default installation. Some additional ports are required for certain services, such as
NTP, or applications that are commonly installed with vCenter Server.
In addition to these ports, you can configure other ports depending on your needs.
