google "DG834G wake on lan"

"Subnet Directed" is "port forwarding" by another name.

Though this seems to need firmware hacking :-(

You don't need to broadcast to the subnet (you just need the machine to
see the magic packet).

You don't need to use the 'standard' port (you just need the machine to
see the magic packet).

If the machine that you want to wake has a static address, you just need
to port forward the incoming port to that address.

So if you've already got (say) ssh forwarded to the relevant machine, a
correct magic packet sent to your external ssh port on your router could
do the trick.

If your router remembers where the relevant machine is (which is what
you circumvent by going to a broadcast packet).

Kind regards,
