I would like to configure my DHCP Server (Windows Server 2008 R2) so that it assigns to each host two gateways. The client should use the gateway which is closer (less number of hops). I can do this manually on the client itself by setting the 'automatic metric' (see print-screen):
But on the DHCP server if I define the router in the Scope-Settings it will use Gateway depending on the priority which is given by the position in the settings.
How can I configure my DHCP Server so that it works like described in the first image?
Thank you in advance for your help!

OK. So you want all of the traffic to go out the closest gateway, but you can't get there from here. It's all the same layer 2/3 network so there's no way to
prioritizethe gateways so that clients use the closest one. If you use different subnets on each side then that presents the wrinkle of having to route traffic between the two subnets so you'd then need to throw a router in the mix, which would necessitate the need to turn the layer 2 connection into a layer 3 connection. IMO, leave it as it is. Define both gateways in DHCP using the DG that you prefer for the traffic to go through at the top of the list, knowing that clients on the other side have a longer trip.
