How can a non - nerd set up a correct firewall?
Possibly a non - nerd that recognizes of the presence of a firewall is currently some sort of a geek. If you have actually been a home windows - customer after that it was instead very easy to set up a firewall (I do not recognize if it was an excellent one!): enable a firewall with maximum defense. After that for each and every program that attempted to make a net - link an alert was revealed (permit or otherwise permit). This way with no anticipation of methods and also ports a customer can set up a firewall that was matched to his demands. Exists any kind of equal program in Ubuntu to make sure that any kind of customer can set up a correct firewall?
