Wake on lan works with Windows 10 but not with Proxmox (debian 11-based)

Hi All,

I confirmed that Wake On Lan (WOL) works with Windows 10 Pro on a Lenovo ThinkStation P310 with onboard Intel I219-LM GB Ethernet controller. I had to make some changes in the adapter settings (eg. disable "reduce speed on power down") and the UEFI BIOS to make it work. I was able to wake up the system from a "Hibernate" or "Sleep" mode by sending a magic packet from another windows host. All good up to here.

I then installed Proxmox 7 (5.11.22-4-pve, which is Debian 11-based) on the same hardware. I can't get WOL to work with Proxmox, no matter what. At this point I am not sure if it is a configuration issue or a BUG?

• The BIOS (is up-to-date) supports WoL and is enabled.
• The NIC supports WoL and is (/was already correctly) enabled and set to "g".

Things I tried:

1. Updated cat /etc/network/interfaces so that at every boot, it sets the vmbr0 interface's wol to "g", using ethtool (see #1 below).
2. Created script to bring the ethernet interface eno1 down properly at shutdown, based on this bug (see #2 below).
3. I also created a systemd service "wol.service", to also set the eno1 interface's wol to "g", using ethtool (see #3 below).

• When the machine is powered on, I successfully tested receiving magic packets using netcat.
• When the machine is powered off, and I send magic packets using apps like "wol" (from a windows host), an android app (landroid), I understand that they are reaching the NIC as I can see the ethernet port flashing, but the machine doesn't boot...

• I tried sending packets to the combination of host's MAC and IP (as well as broadcast to 255.255.255.255), ports 7,9,4343,4000,etc. no luck.

Any suggestions?

[#2] Created script to bring the ethernet interface down properly at shutdown
vi /etc/rc6.d/wol_poweroff.sh
cp /etc/rc6.d/wol_poweroff.sh /etc/rc0.d/wol_poweroff.sh

Script wol_poweroff.sh contains:
#!/bin/bash
ifconfig eno1 down
poweroff

Finally changed permissions to make it executable:
sudo chmod 755 /etc/rc0.d/wol_poweroff.sh && sudo chmod 755 /etc/rc6.d/wol_poweroff.sh
