Similar to Outpost Firewall/Little Snitch for Ubuntu?

Question

linux

I would like to find something like Outpost Firewall(Windows) / Little Snitch(Mac OS) for Ubuntu. Firewall, which catches all connections and pushes a window in which you can allow / deny access. With a more or less normal interface, openSnitch did not enter. Is there any choice at all? What options do you know?

Answer 1

Try Firewalld . There will be no pop-up windows, but it does its job. There are not so many kinds of firewalls in Linux, as a rule, it's just iptable with a GUI, for example Fwbuilder (there is an applet for viewing and editing rules) - this one suits you best.
