This document does not claim to be complete, nor does it claim to be exact. The reason I wrote this document is because I got stuck with setting up SAProuter on a DMZ, with a couple of firewalls. So I collected as much information as I could find and crafted this document so I would have a reference.

Working with some other people on the issue(s) it appeared that I was not the only one wandering in the dark, so I decided to release the document to the world for everybody to shoot at. So shoot, and help to make this document better and more complete.

This document is based on tests done with SAProuter running on Debian GNU/Linux and two Debian GNU/Linux firewalls.
