You can change the VPC only when you are creating the NAT gateway. After the NAT gateway is created, you cannot modify the VPC.
Subnet
The subnet of the VPC that the NAT gateway belongs to.
The subnet must have at least one available IP address.
You can change the subnet only when you are creating the NAT gateway. After the NAT gateway is created, you cannot change the subnet.
Type
