Firewall on Linux is something I still don’t understand, and explanations found on Internet have always confused me. Do you happen to know some good tutorial to share? Or maybe one doesn’t need to do anything at all in distros like Ubuntu?
Thank you ALL for the great advice and guides! I’m writing from behind a laptop firewall now, and don’t notice anything :) It was smoother than I expected. In the end I used UFW because it was already installed, but I’ll take a look at firewalld too in some days! I don’t have any incoming ssh connections (not a server), so I didn’t need to worry about that :)
I don’t think you need to configure your firewall.
Firewalls are usualy used to block incomming connectings. Usualy a Firewall that blocks all incomming connections is already active on your modem/router. Adding exception to the modem/router Firewall usualy happen through port forwords.
Thank you for the advice!

Regarding ssh: you only mean incoming ssh, right?
