Wake on LAN uses IP broadcasts to send messages, by default these packets will not leave the subnet. To send the wake on LAN action to a different subnet you have 3 options:
- Configure your routers to allow directed broadcasts
- Install a separate scanning server on each subnet. (This requires a license that allows more than 1 scanning server)
- Use VLANs to connect your scanning server part directly to each subnet.
