I think this lead me on the right path: https://community.ui.com/questions/Having-trouble-allowing-WOL-fowarding/5fa05081-125f-402b-a20c-ef1080e288d8#answer/5653fc4f-4d3a-4061-866c-f4c20f10d9b9

This is for edgerouter, which is what I use, but I suppose opensense can do this just as well.

Keep in mind, don't use 1.1.1.1 for your forwarding address, use one in your LAN range, just outside of DHCP because this type of static routing will mess up a connection to anything actually on this IP.

This is how it looks in my edge os config:

protocols {
  static {
    arp 10.0.40.114 {
      hwaddr ff:ff:ff:ff:ff:ff
    }
  }
}

10.0.40.114 is the address I use to forward WoL broadcast to.

Then I use an app called Wake On Lan on Android and set it up like this:
Hostname/IP/Broadcast address: 10.0.40.114
Device IP: [actual IP I want to wake up on the same VLAN/physical network]
WOL Port: 9

This works fine if you're using the router as the gateway for both VPN and LAN, but it will get messy with masquarade and NAT - then you have to use port forwarding I guess, and it should work from WAN.

I just wanted it to be over VPN to limit my exposure (even if WoL packets aren't especially scary).
