A NAT Gateway modifies network address information in IP header of packets to remap one IP address into another that will be used from the entire network for all internet connections. This public IP generated, is what the NAT gateway needs in order to function normally and establish data exchange with the web.
NAT Gateway provides both source NAT (SNAT) and destination NAT (DNAT) functions. Source NAT relates a public IP with a VM so that all network devices can use the same IP for internet connections.
NAT gateway supports demanding business applications and provides secure, reliable and high performance connectivity with cross-zone disaster recovery options so that NAT functionality will not be affected in case of failure in a certain network zone.
