Chapter 7 Firewall : Firewall objects : Virtual IPs : UUID Support for VIP : UUID Support for VIP
  
UUID Support for VIP
UUID is now supported in for virtual IPs and virtual IP groups. This includes virtual IPs for IPv4, IPv6, NAT46, and NAT64. To view the UUID for these objects in a FortiGate unit's logs, log-uuid must be set to extended mode, rather than policy-only (which only shows the policy UUID in a traffic log). UUID can only be configured through the CLI
Syntax
config sys global
set log-uuid {disable | policy-only | extended}
end
 
There is another type of address that the term “virtual IP address” commonly refers to which is used in load balancing and other similar configurations. In those cases, a number of devices share a separately created virtual IP address that can be sent to multiple possible devices. In FortiOS these are referred to as Virtual Servers and are configured in the “Load Balance” section.
