Required ports for vCenter Server 5.0

Products

VMware vCenter Server

Issue/Introduction

This article provides information about the required ports for vCenter Server 5.0.

Environment

VMware vCenter Server 5.0.x

Resolution

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

VMware uses designated ports for communication. Additionally, the managed hosts monitor designated ports for data from the vCenter Server system. If a firewall exists between any of these elements and Windows firewall service is in use, the installer opens the ports during the installation. 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.

Note: In Microsoft Windows Server 2008, a firewall is enabled by default.

This table outlines the ports required for communication between components:

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/ . Note: Microsoft Internet Information Services (IIS) also use port 80.
389	This port must be open on the local and all remote instances of vCenter Server. This is the LDAP port number for the Directory Services for the vCenter Server group. The vCenter Server system needs to bind to port 389, even if you are not joining this vCenter Server instance to a Linked Mode group. If another service is running on this port, it might be preferable to remove it or change its port to a different port. You can run the LDAP service on any port from 1025 through 65535. If this instance is serving as the Microsoft Windows Active Directory, change the port number from 389 to an available port from 1025 through 65535.
443	The default port that the vCenter Server system uses to listen for connections from the vSphere Client. To enable the vCenter Server system to receive data from the vSphere Client, open port 443 in the firewall. The vCenter Server system also uses port 443 to monitor data transfer from SDK clients. If you use another port number for HTTPS, you must use ip-address:port when you log in to the vCenter Server system.
636	For vCenter Server Linked Mode, this is the SSL port of the local instance. If another service is running on this port, it might be preferable to remove it or change its port to a different port. You can run the SSL service on any port from 1025 through 65535.
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.
903	Port 903 must not be blocked between the vSphere Client and the hosts. The vSphere Client uses this ports to display virtual machine consoles
8080	Web Services HTTP. Used for the VMware VirtualCenter Management Web Services.
8443	Web Services HTTPS. Used for the VMware VirtualCenter Management Web Services.
10080	vCenter Inventory Service HTTP.
10443	vCenter Inventory Service HTTPS.
10109	vCenter Inventory Service Service Management.
10111	vCenter Inventory Service Linked Mode Communication.
60099	Web Service change service notification port.

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

For a discussion of firewall configuration, see vSphere Security.
