Firewall Rules for View Connection Server
Certain ports must be opened on the firewall for View Connection Server instances and security servers.
When you install View Connection Server, the installation program can optionally configure the required
Windows Firewall rules for you. These rules open the ports that are used by default. If you change the
default ports after installation, you must manually configure Windows Firewall to allow Horizon Client
devices to connect to View through the updated ports.
If you choose to install HTML Access with View Connection Server, the installer configures the VMware
Horizon View Connection Server (Blast-In) rule in Windows Firewall to open TCP port 8443, used by
HTML Access.
The following table lists the default ports that can be opened automatically during installation. Ports are
incoming unless otherwise noted.
