Hi, I wanted to change my MAC address to my parent's firewall MAC Address (dont judge me) in order to access a webpage hosted on my computer instead of the firewall's login page. This works when I do that and loads the Windows IIS page, however when I do this, everyone loses connection to the internet. Why am I unable to access the internet and how can I resolve this?
 
Solution
You can't have two devices on a network with the same MAC address, that causes collisions and plus a firewall mac address isn't like a device mac address - they both server two different functions.
