Talk:HOWTO Iptables and stateful firewalls

From Gentoo Linux Wiki

From the article:

"This HOWTO is heavily based on Dan Robbins Linux 2.4 Stateful Firewall Design which can be found at IBM's Developerworks"

Replace "heavily based on" with "cut and pasted directly from" and we have a winner.

This same document (only slightly updated) also appears on gentoo.org: http://www.gentoo.org/doc/en/articles/linux-24-stateful-fw-design.xml

--Mimosinnet 15:21, 21 March 2007 (UTC) This howto has been really useful for me, and it is more updated (with references to kernel 2.6.20) than the one in gentoo.org. Thanks!

[edit] Small typo and a suggestion

This is a great tutorial about iptables. For me the best thing here is the didactic. The things are very well explained.

--Typo: Change the ${UPIP} to ${NAT} in our enhanced script, router section.

--Suggestion: I think would be good have a section that explain the needed modules that we have to load. In this tutorial there is nothing about iptables modules.

[edit] Lacking Explanation

Where does the ${UPIP} come from? Meaning: Where does it get filled in in the script? I know a fair amount about iptables, but I'd like to know the 'gentoo way'. It seems there is some magic in the background. Can s.o. explain.
