WOL (wak on Lan) for Proxmox-Host not working :(

Hello together, I am a linux-hobbiest and just started using proxmox for private experiments recently.....

It seems I can't get WOL working. Maybe someone can help me :) would be much appeciated....

So what I was able to do:

ethtool -s enp4s0 wol g -> works until next restart/reboot of the system

I edited /etc/network/interfaces and added ethernet-wol g to the file like that:
auto lo
iface lo inet loopback

iface enp4s0 inet manual
    ethernet-wol g
auto vmbr0
iface vmbr0 inet static

if I reboot the system ethtool enp4s0 shows: Wake-on: d

Some can give me an advice? Thank you :)
I had the same problem since I upgraded to VE 6

I had this solution of another forum user.
It works for me. Some workaround for you problem.

apt-get update && apt-get install ethtool

vi /etc/systemd/system/wol.service
Insert the following:

Description=Wake-on-LAN for enp2s0

ExecStart=/sbin/ethtool -s enp2s0 wol g
ExecStop=/sbin/ethtool -s enp2s0 wol g


Save the file

Then type :
systemctl daemon-reload
systemctl start wol.service
systemctl enable wol.service
systemctl is-enabled wol.service

iface enp4s0 inet manual ethernet-wol g

I've also set it on the bridge which the physical port is a slave to.

Instead of the systemd-unit you also could add a post-up command on the interface, e.g.:

auto vmbr0
iface vmbr0 inet static
    post-up /sbin/ethtool -s enp2s0 wol g
Thanks Thomas....diden't know the post-up command in the interfaces-configuration.....seems like a nice way to do it as well....
Thank you to @t.lamprecht for pointing me/us in the right direction.

A little experimentation showed me that adding post-up /sbin/ethtool -s enp2s0 wol g only to the vmbr0 interface is sufficient.
