If I add arp entry in router config like this:

arp add ff:ff:ff:ff:ff:ff

Open specific port:

port: 1009 ip:

Will it broadcast message to all connected devices?

I'm sending wake on lan package.

What if I add random IP like:

arp add ff:ff:ff:ff:ff:ff

port: 1009 ip:

Will it still broadcast to all network devices?

You have a few questions on WoL here - I am still not clear why you want to broadcast. You know the mac you are trying to wake, so why not put that in your arp table? – Paul May 30 '12 at 14:05
Simple. My router deletes ARP entries when they had been utilized and after server had been shutdown. Arp entry in form of IP FF:FF:FF sticks for some reason and I don't have to add it to arp table again and again. – Sandro Dzneladze May 31 '12 at 7:52

I found that arp add ff:ff:ff:ff:ff:ff cannot be done, router gives error.

arp add ff:ff:ff:ff:ff:ff works fine for WOL functionality from WAN.
