I'm using proxmox for a few years and have encountered a problem recently. After a power outage I want to send a WoL package to my intel NUC(with proxmox) but that is not working. I think the problem is that "eno1" has no ip adress to receive the magic packet . I send it to the "vmbr0" mac adress but nothing happens. Also when using ethtool it shows only eno1 supports WoL.
Am I looking in the correct direction and can I just enter an ip adress in eno1 and delete bridge modus in vmbr0 or will my LXC/VM's stop working on the local network? Hope someone can help me. See situation in below image.

Hi,

You know that WOL rely on the MAC address and not the IP address ?

So you need to send the magic packet with your physical MAC NIC to do WOL (and you have to enable WOL on your device, which can be off by default).

Best regards,
 
I do know that it works via mac address :) I have only one NIC on the server but all my containers and vm's have unique mac addresses. My idea was that without ip addres I don't get the mac address. Or is there a way to get it via cli instead?
 
Thanks for your reply! But in my case it is about the host device so above is not working. If there is such a thing as "boot on power restore" then I'm also achieving my goal but can't find that in my bios settings.
 
Hi,

Well, if you want WOL on the host, your NIC and BIOS should support that (and have it enable), and your magic packet need to have your physical NIC MAC address.

Or a don't understand your question since you talk about VM/CT before and now you talk about your host…

Best regards,
 
You do understand my question. I responded to your question about vm/lxc, that's where the confussion comes from maybve... I don't have problems with those. Summary:

I want WoL on my host. WoL is enabled in bios and my NIC supports it. Only problem is I dont have the mac address of my NIC to wake it up and can't find it...
