Hi, Neutron permits to set a gateway IP outside of the subnet cidr by default. And, thanks to the garyk's patch [1], it's possible to change this default behavior with config flag 'force_gateway_on_subnet'. This flag was added to keep the backward compatibility for people who need to set the gateway outside of the subnet. I think this behavior does not reflect the classic usage of subnets. So I propose to update the default value of the flag 'force_gateway_on_subnet' to True. Any thought?
