I had been told to use a firewall to my desktop after the new Linux upgrade which comes with ipv6 enabled by default. So after searching almost two days I found that I have to drop input-output-forward and then open just the ports I need(sounds pretty logical). So my questions are : 1)Which ports do I need to open ? 2)Will this be enough to secure my desktop ? (I am talking about the networking part). Thanks for your time!
