We are trying to Wake Up clients (t5740) on different subnets using HPDM. We get the Warning-Message “The subnet of the device in red color is not the same with its Device Management Gateway”, then we press “Yes” to send the Task anyway, but unfortunately the Client does not wake up.
Wake up Clients with HPDM within the same subnet works perfectly.
Using another WOL-Tool to wake up Clients on different subnets also works perfectly
(sending WOL-Commands to Broadcast-Address xx.xx.xx.255).
IP-Directed Broadcast is enabled on our routers.
Is there a way to make this working with HP Device Manager (HPDM) ?

Also enable UDP Port 2304.
If you are using a Cisco Switch you should add this line:
"ip forward-protocol udp 2304"

I was told by someone in HP that this cannot be done. You have to have a Gateway on each subnet.
If you have this working without please let me know. We have Wake on Lan working for other things just not HPDM.
We have a single HPDM and gateway in out server room, but no thin clients on the server room subnet so pointless.

I hope this is not the case, as we have many different facilities many of which have different subnets per floor we would need many many dozens of gateways for that then.

We have no Ports blocked on our routers.
WOL over different subnets still not working with HPDM.
In the meantime we use an other tool to wake up the clients, which is of course not a fine solution, as we want to use HPDM for all tasks.

Just a heads up to anyone else looking at this I can confirm there is a 3rd party WOL tool called MC-WOL that will wake up HP ThinClients outside of the host subnet.

WOLCMD.EXE is another (freeware) WOL-Tool which is able to wake up devices across subnets.
HP should modify HPDM to allow the WOL-Transmission method = "Subnet-directed broadcasts" as an option.
