2. Where is the official Web Site? Is there a Mailing List?

There are three official sites:

• Thanks to Filewatcher.
• Thanks to The Samba Team and SGI.
• Thanks to Harald Welte.

You can reach all of them using round-robin DNS via http://www.netfilter.org/ and http://www.iptables.org/

For the official netfilter mailing list, see netfilter List.
