Required ports for ESXi 5.1.x (2039095)

Purpose

This article outlines the required ports for using and accessing an ESXi 5.1 host. In addition, ports that are necessary to access external components, such as storage devices, management systems, etc, are listed. Ensure that these ports are open to access these components.

Note: If you are attaching your ESXi 5.1 host to vCenter Server, additional ports will be required. For more information, see Required ports for vCenter Server 5.1 (2031843).

Resolution

ESXi must be able to send and receive data from every vSphere Client. If you are attaching your ESXi host to vCenter Server, additional ports will be required. To enable migration and provisioning activities between managed hosts, the source and destination hosts must be able to receive data from each other.

Also, if you are attaching your ESXi host to external storage components, such as an NFS or iSCSI device, or management components, such as a SysLog server, monitoring system, etc, additional ports must be opened on the firewall in those instances.

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

This table outlines the ports required for communication between these components:
