When load balancing, FortiADC can apply static or dynamic network address translation (NAT). In addition to specifying which source addresses in the IP layer will be translated, you can also specify the network interface for packet egress (Out Interface).
To configure how FortiADC will rewrite source IP addresses in packets that it receives before forwarding them, go to Firewall > NAT > SNAT. Selecting IP will result in static NAT; Selecting Pool will result in dynamic NAT.
