Public NAT Gateway Overview¶
Public NAT gateways provide network address translation with 20 Gbit/s of bandwidth for ECSs in a VPC, or servers in on-premises data centers that connect to a VPC through Direct Connect or VPN, allowing these servers to share EIPs to access the Internet or provide services accessible from the Internet.
The process of using a public NAT gateway is as follows:

Note
An SNAT rule and a DNAT rule cannot share the same EIP. Therefore, if you need to create an SNAT rule and a DNAT rule separately, assign two EIPs.
