The VMware vCenter Server system must be able to send data to every managed host and receive data from every vSphere Web Client. For migration and provisioning activities between managed hosts, the source and destination hosts must be able to receive data from each other.

For information about ports required for vCenter Server on Windows, see Required Ports for vCenter Server.

VMware uses designated ports for communication. Additionally, the managed hosts monitor designated ports for data from the vCenter Server system. The vCenter Server Appliance is preconfigured to use the ports listed in 1. For custom firewalls, you must manually open the required ports. If you have a firewall between two managed hosts and you want to perform source or target activities, such as migration or cloning, you must configure a means for the managed hosts to receive data.

Table 1. Ports Required for the vCenter Server Appliance

Port

Description

80

vCenter Server requires port 80 for direct HTTP connections. Port 80 redirects requests to HTTPS port 443. This redirection is useful if you accidentally use http://server instead of https://server.

443

The vCenter Server system uses port 443 to monitor data transfer from SDK clients.

902

The default port that the vCenter Server system uses to send data to managed hosts. Managed hosts also send a regular heartbeat over UDP port 902 to the vCenter Server system. This port must not be blocked by firewalls between the server and the hosts or between hosts.

8080

Web Services HTTP. Used for the VMware VirtualCenter Management Web Services.

8443

Web Services HTTPS. Used for the VMware VirtualCenter Management Web Services.

To have the vCenter Server system use a different port to receive vSphere Web Client data, see the vCenter Server and Host Management documentation.

For a discussion of firewall configuration, see the vSphere Security documentation.
