A public NAT gateway provides SNAT and DNAT so that cloud servers in a VPC can share an EIP to communicate with the Internet. A private NAT gateway allows cloud servers in a VPC to share the same private IP address to access or provide services accessible from an on-premises data center or a remote VPC.
