I am running Mac OS X Server 10.6 on my iMac and I am wondering how to multihome a Mac. I know it's possible to accomplish this by using both Wi-fi and Ethernet, but I just want to use Ethernet. Any idea how to set this up? Thanks.

  • What do you hope to achieve? Do you have two networks or two internet services that you wish to use?

  • Yes, I would like to run two websites on the server. Dec 19, 2011 at 1:23
  • You can also use name-based virtual sites to avoid the need for multihoming. Dec 19, 2011 at 22:52

Got it. All you have to do is add multiple Ethernet interfaces in Network Preferences. And then just configure each one to the correct settings and you're set to go. I tested this by hosting two different websites on two different IPs by multihoming my iMac and it worked!

  • System Prefs -> Network dialog
  • Press the + button and select the interface you want to add to (you may need to go back and identify which one if you have multiple Ethernet ports).
  • Name the service and press "Create"
  • Configure the new service as you would a static (manual) interface
  • Click "Apply"
