Hi. I was in the middle of securing my router when I read that I needed the MAC addresses of my machines. I looked on my macbook and in the "About this Mac" section, I came across three MAC addresses, one for bluetooth, ethernet, and airport. which of these do I use ? all three ? I'm trying to fill in the section to control access via MAC addresses. Just FYI.
The MAC address(es) of whatever you're using to connect to the router. I'd guess airport, and maybe ethernet. probably not bluetooth.
