Mac OS X Mountain Lion cannot share internet connection because of 802.1X protection My notebook is connected on Ethernet using 802.1X. When I try to share the internet via Wifi I get the error message Your Internet connection cannot be shared because its protected by 802.1X

I dont have right now a option of not using a protected network. Is there a way to share the connection? I want to create an adhoc wifi network to test my devices.
I agree with Gordon. The 802.1X security measures are in place for a reason. You should contact your IT team to see if they have other options for you or if they can set up a guest network. In the absence of that, I would recommend getting a MiFi from your carrier or turning your smartphone into a wireless hotspot. If you have access to LTE, it may be faster than your office WiFi.
