VNC connect mode is when the system being installed initiates a connection to the VNC viewer running on a remote system. Before you start, make sure the remote system is configured to accept incoming connection on the port you want to use for VNC. The exact way to make sure the connection will not be blocked depends on your network and on your workstation's configuration. Information about configuring the firewall in {PRODUCT} is available in the [citetitle]_{PRODUCT} Security{nbsp}Guide_, available at link:++https://docs.fedoraproject.org/++[].
VNC Direct Mode is when the VNC viewer initiates a connection to the system being installed. [application]*Anaconda* will tell you when to initiate this connection.
When installing headless systems, the only choices are an automated Kickstart installation or an interactive VNC installation using connect mode. For more information about automated Kickstart installation, see xref:appendixes/Kickstart_Syntax_Reference.adoc#appe-kickstart-syntax-reference[Kickstart Syntax Reference]. The general process for an interactive VNC installation is described below.
When the connection is successfully established, a new window will open on the system running the VNC viewer, displaying the installation menu. This window will provide full remote access to the installer until the installation finishes and the system reboots for the first time.
When this message is displayed, the VNC viewer is ready and waiting for an incoming connection from the installation system.
You can then proceed with xref:install/Installing_Using_Anaconda.adoc#chap-installing-using-anaconda[Installing Using Anaconda].
