How could I filter a single IP address or a range of IP addresses to prevent them from accessing my computer?
I would like to block them from accessing my computer without additionnal conditions.
I know that one can use
iptables in this situation, but I am unaware of the exact syntax, how to make the changes permanent, and which command to run in order to launch the
iptables service at startup. I also don't want to make mistakes that may break my access to the Internet.
