What does the FortiGate ‘set nat enable’ command do in a firewall policy?

The ‘set nat enable’ command in a FortiGate firewall policy enables Source NAT (SNAT) for outgoing traffic, typically rewriting the source IP to the FortiGate’s interface IP or an IP pool. It does not disable NAT (B), force a specific pool (C), or limit to incoming traffic (D). Exact extract: "The ‘set nat enable’ command in a firewall policy enables Source NAT, rewriting the source IP address of outgoing traffic to the egress interface IP or a configured NAT pool."
