Bug Description
See bug 1375990.
The fix for that bug had to be backed out because it broke the case where
the VNs were extended to the SDN GW and beyond. The reason being that the
SDN GW cannot send traffic down the correct service chain without filter
based forwarding (FBF) configuration.
This bug limits the scope of the problem as follows:
1. The left VN is not extended to the SDN GW or beyond i.e. all source in
the left VN lie within the DC.
2. The right VN is not extended to the SDN GW or beyond OR the the last
service in all the service chains between the VNs is a NAT service. This
ensures that return traffic from outside the DC will always go back to
the correct service chain.
On account of these limitations, the new functionality needs to be enabled
explicitly by setting a new property on the left VN.
