Certain network ports must be opened on the Windows firewall for the Cloud Pod Architecture feature to work. When you install View Connection Server, the installation program can optionally configure the required firewall rules for you. These rules open the ports that are used by default. If you change the default ports after installation, or if there are other firewalls in your network, you must manually configure the Windows firewall.

Table 1. Ports Opened During View Connection Server Installation

TCP Port



The Global Data Layer LDAP instance runs on this port. Shared data is replicated on every View Connection Server instance in a pod federation. Each View Connection Server instance in a pod federation runs a second LDAP instance to store shared data.


The View Interpod API (VIPA) interpod communication channel runs on this port. View Connection Server instances use the VIPA interpod communication channel to launch new desktops, find existing desktops, and share health status data and other information.
