I have a server connected to the internet.
There is a router between the server and the Internet.
I need to let one computer into my internal network.
I'm not really interested in a VPN.
Should I allow that computer in by configuring the router to allow only one IP or should I configure it to allow one MAC adddress in?
I heard you can spoof a MAC address?
Can you also spoof an IP?
What should I do?
