Re: Debian as a router.

[Mal Beaton <mal@mbeaton.id.au>]

I have posted the interim howto on
http://mbeaton.id.au:5537/debian/

I have a few updates to do on the documentation as I have been slack

If anyone can find any glaring errors or omissions please let me know

experience in trying to put it all together
