I have a windows domain network with two different subnets. Both are connected trough VPN gateways.
DHCP and default gateway is an exiting router blackbox. Unfortunately I have very limited control over it. It is not possible to add a route there or add such an DHCP option. So I need to teach all Computers (Domain Members) how to reach the remote net. A simple 'route add' would do the trick. But I want to set the route without touching each machine.
The closest idea I had would be a startup script deployed via GPO. It would add the routings to all remote networks except the local network. But I am not sure how to implement the logic.
