The installation and configuration process for the first Horizon Connection Server, referred to as a Horizon Standard Connection Server during installation, requires some amount of preparation. This section will outline what is required prior to beginning the installation.
If your organization requires that a firewall or other network controls be placed between your internal Horizon clients and your Connection Servers, consult the Horizon documentation (https://docs.vmware.com/en/VMware-Horizon-7/index.html) for a comprehensive list of all firewall ports required when implementing a Horizon Connection Server.
