I have been looking for a way to block all my applications from accessing the internet except for 1 or 2 chosen applications.I looked into Uncomplicated Firewall (ufw) and its respective Gui (gufw):but gufw doesn't seem to have the option to block specific programs from accessing the internet (which windows firewall does with outbound rules).QUESTION: Does anyone know how I might be able to get that done?
