Linux Mint 17.2.
I want to prevent a machine establishing a connection to a specific IP address on the internet. It would take to long to explain why, but it's legit- I just don't have control over the app that's doing it.
I looked at iptables and I'd be waaay out of my depth, anyone know if I could do it with GUFW?
It looks easy enough, but I've heard that before...
