Establishing a VPN connection to a VPC in another region

To establish a VPN that allows instances on the VPC subnet(s) that sit behind a Netgate appliance to communicate with instances that reside in a VPC in another region, the Netgate appliance has a VPC configuration wizard that assists by configuring both the Netgate appliance as well as the VPC configuration elements that would normally have to be set manually through the AWS Management Console.

For detailed instructions, see the AWS VPC User Guide.
