Send Wake-On-LAN packet from the on-prem server
Having the "relay" to send WOL packets is a neat feature but does not work if no machines are active on the subnet. If the on-premise server was able to send WOL packets, that would help in the event there are no relays online.
Hello,
If an access client is installed on the server, and the server is on the same LAN as the offline machine you want to wake, then, I think, you'll achieve what you're asking for.
If this is not what you're asking for, please provide more details.
