I have two VPCs setup, one in Sydney and another Oregon.
From my datacenter I have a VPN connection into the Sydney VPC.
A routing rule exists in my Sydney VPC to route all traffic to the Oregon subnet via a VPN instance.
Between the Sydney and Oregon VPCs I have an IPSEC connection which is working correctly. (http://aws.amazon.com/articles/5472675506466066).
I am now trying to route traffic to the subnet in Oregon via the Sydney VPC from the datacenter. The virtual private gateway is unable to route the traffic from the VPN connection to the subnet in Oregon.
Is there any way to get the virtual private gateway to route traffic to a subnet that is not part of the target VPC CIDR?
