[LUG] Roll-your-own firewall

[Jonathan Melhuish <lists@xxxxxxxxxxxxxxxx>]

I'm trying to "roll my own" block-everything-external type firewall, based 
loosely on Kai's instructions at:

http://db.cs.helsinki.fi/~hendry/faqwiz/faqw.py?req=show&file=faq01.020.htp

However, I'm falling at the first hurdle:

[root@xxxxxxxxx jon]# iptables -F
[root@xxxxxxxxx jon]#  iptables -A block -m state --state NEW -i ! ppp0 -j 
ACCEPT
iptables: No chain/target/match by that name

What does that mean?  Makes no sense to me, I thought I was trying to *make* a 
chain or filter or something...

Cheers,

Jon
PS:  Is there any way I can post from "jon@xxxxxxxxxxxxxxxx" but have my list 
emails delivered to "lists@xxxxxxxxxxxxxxxx"?
