Chapter 1 What’s New for FortiOS 5.2.1 : System Features : FortiGuard Services : FortiGuard Server List
  
FortiGuard Server List
In FortiOS 5.2, you can create a server list for receiving FortiGuard updates, allowing you to use different servers for different FortiGuard services. Each server can be used for either web filter and anti-spam ratings or AV/IPS signature updates.
The server list also has the ability to include the default servers by adding them to the end of the list. This option is only available if the central management type is not set to FortiGuard.
If no server list is configured, the FortiGuard will not use the public FortiGuard servers as resolved by DNS.
Syntax
config server-list
edit <ID>
set server-type {rating | update}
set server-address <address>
end
set include-default-servers {enable | disable}
end
