Thomas Woerner (iptables maintainer) is currently working on a prototype
for basically the next generation of firewalling. He'll put up the code
later this week with docu and all that shizzle as he just finished the
first prototype of it a week ago. It's by far not complete yet, but
it'll show enough of what you can do with it with some nice features and
Basically it's a statefull firewall daemon now that allows us to support
and implement a lot of those features which have been so critically
missing in our old way of doing firewalls (aka static crap) and
basically impossible to do there. One example is libvirt and how it has
to change firewall rules dynamically depending on whether a guest is
started or shut down, and those rules should survive a restart of the
firewall (which currently they don't and can't). Roughly speaking it's a
bit similar with the switch from our static initscripts for network
configuration to NetworkManager and how it deals with network interfaces
A bit more initial info can already be found here:
but he'll send out a much more detailed description of what the new
firewalld will be able to do and what problems we can solve with it.
One thing is e.g notifications to users when some service/app requests
to open a port. First version won't have network zones yet, but he and
Dan Williams are working on that for the next generation which will then
basically allow it to let the user decide once for each
interface/connection what should happen with it and never be bothered
with it afterwards.

Sounds interesting, thanks Phil!
