So I have been messing around with firewalld in fedora and a few iptable frontends in ubuntu...


but


I still haven't found a way to restrict traffic just they way I like: only allowing outgoing connections from ports 80 and 443.


not only that what I really like is interactive firewalls that flag every single process that tries to establish a connection.

Is there anything like that in the linux ecosystem?

firewallbuilder just confused the shit out of me and UGFW doesn't allow whitelisting only blacklisting.


Fedora's firewall seems good but even when I deselect all services and reject icmp I don't really know how to restrict it to ports 80 and 443
