The Amazon Virtual Private Cloud lets you securely isolate a portion of the AWS cloud for your own private use. By using a Virtual Private Network connection, you can link your VPC to an existing on-site network.
Now, AWS is adding some further upgrades to enhance these services:
Network Address Translation (NAT) allows you to match a range of IP addresses with another set. This effectively lets you map your VPN device (customer gateway) from a private to a public IP.
NAT Traversal does things better by letting your customer gateway connect to your Virtual Private Gateway (VGW). Essentially you can create IP connections that begin from a NAT device on premise and connect to a Virtual Private Cloud using translated addresses.
More Encryption Options
As the VPC’s VPN is connecting to your on-premises VPN, it can suggest encryption options of varying strengths for you to choose from (such as AES256 instad of AES128). Both sides will use a Diffi-Hellman key exchange in order to establish a secure connection. You can thereby determine how strong you want your encryption to be.
Reusable CGW IP addresses
You can now reuse any pre-existing IP address for your customer gateway connections. No need to give a specific IP address every time.
