TCP and UDP Ports for Management Access

This section lists predetermined TCP and UDP ports used for management access to your VirtualCenter Server, ESX Server hosts, and other network components. If you need to manage network components from outside a firewall, you might need to reconfigure the firewall to allow access on the appropriate ports.

Note

The ports listed in the table are connected through the service console interface unless otherwise indicated.

Table 10-1. TCP and UDP Ports

The default non-secure TCP Web port typically used in conjunction with port 443 as a front end for access to ESX Server networks from the Web. Port 80 redirects traffic to an HTTPS landing page (port 443) from which you launch your virtual machine console.

Use port 80 for connection to VI Web Access from the Web.

Incoming TCP

443

HTTPS access. (See Update)

The default SSL Web port. Use Port 443 for the following:

•	Connection to VI Web Access from the Web.

•	VI Web Access and third-party network management client connections to the VirtualCenter Server.

•	Direct VI Web Access and third-party network management clients access to ESX Server hosts.

Incoming TCP

902

Authentication traffic for the ESX Server host and virtual machine configuration. (See Update)

Use Port 902 for the following:

•	VI Client access to the VirtualCenter Server.

•	VirtualCenter Server access to ESX Server hosts.

•	Direct VI Client access to ESX Server hosts.

•	ESX Server host access to other ESX Server hosts for migration and provisioning.

Incoming TCP, outgoing UDP

903

Remote console traffic generated by user access to virtual machines on a specific ESX Server host.

Use Port 903 for the following:

•	VI Client access to virtual machine consoles.

•	VI Web Access Client access to virtual machine consoles.

Incoming TCP

2049

Transactions from your NFS storage devices.

This port is used on the VMkernel interface rather than the service console interface.

Incoming and outgoing TCP

2050–5000

Traffic between ESX Server hosts for VMware High Availability (HA) and EMC Autostart Manager.

Outgoing TCP, incoming and outgoing UDP

3260

Transactions from your iSCSI storage devices.

This port is used on the VMkernel interface and the service console interface.

Outgoing TCP

8000

Incoming requests from VMotion.

This port is used on the VMkernel interface rather than the service console interface.

Incoming and outgoing TCP

8042–8045

Traffic between ESX Server hosts for HA and EMC Autostart Manager.

Outgoing TCP, incoming and outgoing UDP

27000

License transactions from ESX Server to the license server.

Outgoing TCP

27010

License transactions from the license server. (See Update)

Incoming TCP

Note

ESX Server and VirtualCenter use ports 8085, 8087, and 9080 internally. For ESX Server, ports 8085, 8087, and 9080 are protected because they don’t accept remote connections.

In addition to the TCP and UDP ports just discussed, you can configure other ports depending on your needs:

•	You can use VirtualCenter to open ports for installed management agents and supported services such as SSH, NFS, and so forth. For information on configuring additional ports for these services, see Opening Firewall Ports for Supported Services and Management Agents.

•	You can open ports in the service console firewall for other services and agents required for your network by running command line scripts. For more information, see Service Console Firewall Configuration.
