Using Virtual IPs (VIPs)
- Use the external IP of 0.0.0.0 when creating a VIP for a FortiGate unit where the external interface IP address is dynamically assigned.
- Be sure to select the correct external interface when creating a new virtual IP (VIP). The external interface should be set to the interface at which the FortiGate unit receives connection requests from external networks.
