During installation, View services are set up to listen on certain network ports by default. In certain organizations, these ports must be changed to comply with organization policies or to avoid contention. You can change the default ports that are used by Connection Server, security server, PCoIP Secure Gateway, and View Composer services.

Changing ports is an optional setup task. Use the default ports if your deployment does not require you to change them.

For a list of the default TCP and UDP ports that are used by Horizon 7 servers, see the Horizon 7 Security document.
