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 your network has other firewalls, you must manually configure the Windows firewall.

Table 1. Ports Opened During View Connection Server Installation
TCP Port Description
22389 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.
8472 The View Interpod API (VIPA) communication channel runs on this port. View Connection Server instances use the VIPA communication channel to launch new desktops and applications, find existing desktops, and share health status data and other information.
