Solved: OpenSnitch, https://github.com/evilsocket/opensnitch available via Software Manager on Mint as well.
There was a windows firewall (tinywall?) that worked like this:
- Something wouldn´t work on the internet.
- I’d query the firewall to see what was just blocked.
- I’d whitelist that traffic.
Pretty painless and I never was forced to think about the firewall until absolutely necessry, and then only to the least possible amount.
Is there any firewall on Linux that works similarly? Running Mint.
ufw’s all i know.
too lazy to look further.
i’m guessing you want a gui…?
idk if it has that, too lazy to look into it.
ufw just works.
(PS, I also use someonewhocares’s hosts file (with my own additions up top). May interest, for a lazy painless way of blacklisting at least, and doing other redirects, and more.)
