Binding an EIP to a NAT Gateway

Scenario

After an EIP is bound to a NAT gateway and SNAT and DNAT rules are added, multiple servers (such as ECSs and BMSs) can use the same EIP to access the Internet and provide services accessible from the Internet.

An SNAT rule allows servers in a specific VPC subnet to use the same EIP to access the Internet.

A DNAT rule enables servers in a VPC to provide services accessible from the Internet.
