When you create a NAT Gateway, you can select a public NAT Gateway and a private NAT Gateway. You can create up to five per zone, and the features of each NAT Gateway are as follows.

- It has both private IPs and a public IPs.
- It uses the public IPs assigned in Public IP for outbound communication to the Internet.
