Microsoft Loopback interface: Bridging or Sharing?

[igorfi]

Hi Guys!

Could you tell me what's the difference between these two? When I select two interfaces - a Loopback and Wireless card, I can select "Bridge", so that they can communicate. But another option is to select properties on WiFi card and select "Share this interface with the Loopback interface. So what is the difference and when to use one or another?

Thank you.

I believe the loopback interface is for testing purposes only, to determine if the device itself is working.

Hi why_wolf. Yes, I know this. I'm using it for GNS3 to connect to the outside world. But what is the difference between Sharing and Bridging?
