Chapter 16. Managing Networks and Traffic

194

Provide the following information:

•Name: A unique name for the VPN customer gateway you create.

•Gateway: The IP address for the remote gateway.

•CIDR list: The guest CIDR list of the remote subnets. Enter a CIDR or a comma-separated

list of CIDRs. Ensure that a guest CIDR list is not overlapped with the VPC’s CIDR, or another

guest CIDR. The CIDR must be RFC1918-compliant.

•IPsec Preshared Key: Preshared keying is a method where the endpoints of the VPN share

a secret key. This key value is used to authenticate the customer gateway and the VPC VPN

gateway to each other.
