[Solved] Dedicated NIC for WOL

[joelones]

I have a pfsense VM, which is my main router and a second bare metal pfsense box which is my backup and is normally powered off.
 
I'd like to automate some sort of failover in the event that the pfsense VM shuts down or I have to bring down the array.
 
My backup pfsense box has a quad which appears to not respond to wake on lan packets, however it does have an onbaord unused realtek nic. Similarly my unraid box has an unused realtek nic as well. Because of port limitations on my switch, I'd like to simply connect both of the realtek NICs with a patch cable and attempt to send a wol packet via this interface from unraid.
 
1) what wol utility should I use on unraid?
2) is there a way to send out the magic packet via a specific interface (in this case eth2 on unraid)?

3) how should the eth2 nic on unraid be configured, do I need an ip address?

4) how can I trigger the wol packet with the pfsense VM goes down?

Thanks @gridrunner.

 

In fact, etherwake has an interface option with the -i parameter but my motherboard doesn't reliably stay off with WOL Lan enabled for some reason ie: it reboots after I halt pfsense, I would hate the scenario where both pfsense boxes are up at the same time.. too bad.
