Wake On LAN not working - Arp cache, unicast, direct broadcast

CMax

Our Cisco network (attached) will allow me to WOL computers across our subnets, but this will not work after 4 hours (in the morning).

 

Server with WOL software = 172.16.0.112

Example of workstation to wake = 172.16.10.*

 

I have done some research but I’m still not confident what settings I would need to change to get this working. What should I adjust and where - Arp cache, Unicast, direct broadcast?

 

 Any advice would be greatly appreciated, and will save the planet of energy wastage :)

 

Best regards

Thank you for the support.

 

I managed to get the WOL working simply by adding an IP Helper on the VLANs and Enabling Directed Broadcast on the edge switches.

 

Only problem now is Windows 8/10 no longer support WOL from S4 and S5 sleep states.
