Make sure you have turned on IP directed-broadcast on the layer-3 device that is doing the routing between the two VLANs you are concerned with.

Also, you are talking about two different packet formats; sometimes it is sent with Ethertype 0x0842, when it won't be routable between VLANs, and sometimes it is sent as an UDP broadcast.

 

It's probably worth checking that whatever is sending the WOL packets is configured to send UDP format packets to the correct subnet broadcast address. I would personally want to confirm that with a packet sniffer, before wondering why they aren't appearing on the far side of the router.

hi,

  so I wonder where should I put the sniffer? Should I place at the layer 3 trunk port to check it whether it used the correct UDP port and broadcast to send out the wol packet? Correct me if I'm wrong.

 

Thanks
