• 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.
