NSX Edge provides network address translation (NAT) service to assign a public address to a computer or group of computers in a private network. Using this technology limits the number of public IP addresses that an organization or company must use, for economy and security purposes. You must configure NAT rules to provide access to services running on privately addressed virtual machines.

The NAT service configuration is separated into source NAT (SNAT) and destination NAT (DNAT) rules.
