Certain network ports must be opened on the Windows firewall for the Cloud Pod Architecture feature to work. When you install 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 Connection Server Installation
Protocol TCP Port Description
HTTP 22389 Used for Global Data Layer LDAP replication. Shared data is replicated on every Connection Server instance in a pod federation. Each Connection Server instance in a pod federation runs a second LDAP instance to store shared data.
HTTPS 22636 Used for secure Global Data Layer LDAP replication.
HTTPS 8472 Used for View Interpod API (VIPA) communication. 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.
Note: Microsoft Windows Server requires a dynamic range of ports to be open between all Connection Server instances. These ports are required by Microsoft Windows for the normal operation of Remote Procedure Call (RPC) and Active Directory replication. For more information about the dynamic range of ports, see the Microsoft Windows Server documentation.
