Creating a Private NAT Gateway¶
Scenarios¶
You need a private NAT gateway to enable servers in your VPC to access or provide services accessible from on-premises data centers and other VPCs.
Notes and Constraints¶
Manually add routes in a VPC to connect it to a remote private network through a VPC peering connection, Direct Connect, or VPN connection.
SNAT and DNAT rules cannot share a transit IP address.
The total number of DNAT and SNAT rules that can be added on a private NAT gateway varies with the private NAT gateway specifications.
Small: 20 or less
Medium: 50 or less
Large: 200 or less
Extra-large: 500 or less

When you create a private NAT gateway, you must specify its VPC, subnet, and specifications.
