Section 6.9.14
Managing Masquerade and SNAT Settings
Masquerading and Source Network Address Translation (SNAT) are forms of dynamic Network Address Translation
(NAT). Both hide a subnetwork behind a single public IP address.
Masquerading is used when the ISP provides a dynamic IP address. SNAT is used when the ISP provides a static IP
address.
