[TUTORIAL] Wake On LAN (WOL) for VMs and Containers

[dbinnunE3]

you have to configure it to watch the vmbr that is connected to your pfSense system sending the packets.

did you modify the script based on the pfsense WoL port number?

pfSense is on vmbr2. i have modified the script with both the interfaces (vmbr0 and vmbr2) but no success. also use port 40000 instead of 9. if you look at the script it basically does a lookup for the mac address you are sending the wol packet to, and then attempts to start the vm which has that "virtual" nic with that mac address. so not sure if the interface (vmbr0 or vmbr2) should really matter, as long you have one of them to route your packet to the mac address. i could be wrong though.

What does the debug output show if you watch it from the console when you send a WoL packet?

so the udp port needs to be 9 and not 40000....doh!

works fine, on local network and remote with tailscale

I use this WOL or Wake on LAN blog post.

Great script, it's working like a charm.
Is there any possibility to have that script listening on port 9 AND 40000 so normal clients and OPNsense can wake up vms?

Or shall I simply create another script with the 2nd port set?!

Best, goeste
