An Ubuntu Firewall

[Randy Wallace]

Ubuntu needs an Ubuntu-Specific Firewall, similar to the OS X implementation.
Firestarter does a good job, but I think it can be done better.
Notably:
Networking, Routing, Services, and Firewalling should be configured
from ONE tool.
There should be support for more than two interfaces.
There should be support for multicast, incl. mDNS, etc...
It should be easy, but include the features that a power user requires.
There should be a simple debug-type tool to recognize when services are blocked.
It should be secure.

I think this would be a great addition to Ubuntu.

I'm looking for an opinion from the community, particularly involving
whether or not I should
attempt to start this project.  It would be a lot of work, and I don't
want to do it in vain.
