Chapter 10 Install and System Administration for FortiOS 5.0 : Advanced concepts : FortiClient discovery and registration : FortiClient discovery
  
FortiClient discovery
You can configure a FortiGate interface as an interface that will accept FortiClient connections. When configured, the FortiGate unit sends broadcast messages which the FortiClient software running on a end user PC is listening for.
To enable the broadcast message
1. Go to System > Network > Interface.
2. Edit the interface to send the broadcast messages.
3. Select FCT-Access.
4. In Device Management, select Broadcast Discovery Messages.
5. Select OK.
Once enabled, the FortiGate unit broadcasts a discovery message that includes the IP address of the interface and listening port number to the local network. All PCs running FortiClient on that network listen for this discovery message.
You also have the option of including a registration key. When the FortiClient discovers the FortiGate unit, it is prompted to enter a registration key, defined by the administrator.
To add a registration key
1. Go to System > Config > Advanced.
2. Select Enable Registration Key for FortiClient, and enter the key.
3. Select Apply.
Ensure you distribute the key to the users that need to connect to the FortiGate unit.
