[linux-help] ipchains permanency

[Nathan <ncozzens@xxxxxxxxxxxxxxxx>]

I'm trying to understand and use ipchains to filter 
packets on my masquerading, dual NIC Potato. :)

The IPCHAINS-HOWTO (in the Making Rules Permanent 
section) saus to use this command to see what rules 
are currently in place:

ipchains-save > /etc/ipchains.rules

It then tells me to create a script that runs every 
time I boot....putting the ipchians rules in place 
just before the NICs becomes active.

But when I ran the command above, there were already a 
bunch of rules in place.  WHERE'D THEY COME 
FROM?  I've been grepping to try and find out, but 
have learned nothing.  Did ipmasq put them 
there?  Will I screw up ipmasq if I start creating my 
own chains?  I still don't understand the ipmasq 
rules....just a bunch of files in a directory.  I can 
tell the masq rules are working, but I don't know 
about the deny rules.  Anyone have a good place for me 
to read about Debian ipmasq rules?

I'm following the directions in the IPCHAINS-HOWTO 
(somewhat blindly).  I just don't want to mess 
something up with my Potato because I was following 
directions for a Red Hat or something.

Thanks,
Nathan
