Port Forwarding for Wake On Lan


I have a a Peplink Balance_E63E. I had setup the port forwarding for other applications with no issues (web server, ip cameras etc…). I know there is an option for WoL from the router gui but would like to set the Port forwarding on port 7 (or any port) and have the ability to trigger wol from anywhere. I tried to set firewall rule but still no luck.
Is this different since im forwarding to to the broadcast subnet (
I’ve tried to forward directly to that Machine’s Ip also no luck.

Please advise.
