Send WoL signal though Opnsense networks (lemmy.ml)

So i dont know what im doing wrong. I have 3 interfaces on opnsense

1:Server=192.168.40.0 2:Wlan=192.168.20.0 3:wireguard=192.168.60.0

And lastly the Wan with its default configuration.

I want to be able to Send a WOL packet though the Wlan network to wake up my PC that is inside Server network.

In Firewall>rules>Wlan I made a new rule like this: Action=Pass Interface=Wlan Direction=in TCP/IP=ipv4 Protocol=UDP Source=any Destination=Server address Destination port range=from 7 to 7

When i try sending a wol signal when my pc went to sleep a few minutes later i think the firewall rule goes though, but when i try to send from another device after lots of time later it doesn't go though i think.

Im using Moonlight to send its signal, does anyone have been thought this problem. Thank you

Update: I have installed the wol plugin from opnsense into my machine, you asked if i can send a wol packet though the router and so in my thinking i was able to do it via the plugin. The problem starts on the ARP, i found what it is and what it do but i dont know how i can insert the MAC address into the firewall rule that i created above, if you dont mind could you help me on how can i do it? And if i do that will i be able to send the wol signal though the Wlan or Wireguard in the future? Thanks

From a Linux command line it would be the command called arp, you need to add a static arp entry. I don’t know how that works on sense, but on Linux it would be something like arp -s IP MAC

Maybe there’s a module in opnsense to help. The way I’ve done this before is using a machine connected to the same network at my target to wake up by logging into that machine and issuing the wake command.
