To configure the vCenter Server system to use a different port to receive vSphere Web Client data, see
the vCenter Server and Host Management documentation.
For more information about firewall configuration, see the vSphere Security documentation.
DNS Requirements for the vCenter Server Appliance and
Platform Services Controller Appliance
When you deploy the new vCenter Server Appliance or Platform Services Controller appliance, in the
temporary network settings, you can assign a static IP address and an FQDN that is resolvable by a DNS
server. After the upgrade, the appliance frees this static IP address and assumes the network settings of
the old appliance.
When you deploy the vCenter Server Appliance or Platform Services Controller appliance with a static IP
address, you ensure that in case of system restart, the IP address of the appliance remains the same.
Before you deploy the vCenter Server Appliance or Platform Services Controller appliance with a static IP
address, you must verify that this IP address has a valid internal domain name system (DNS) registration.
When you deploy the vCenter Server Appliance, the installation of the Web server component that
supports the vSphere Web Client fails if the installer cannot look up the fully qualified domain name
(FQDN) for the appliance from its IP address. Reverse lookup is implemented using PTR records.
