Is there a way (such as an iptables match) that allows one to specify
more than one IP address for one rule?  I have in mind something like
the multiport patch -- allowing the user to specify multiple tcp / udp
ports per rule.  For example, I have the following ruleset that I would
like to convert into one rule:

iptables -N BADGUYS
iptables -A BADGUYS -s 192.168.10.1    -j RETURN # 192.168.10.1 not bad
iptables -A BADGUYS -s 192.168.10.0/24 -j DROP
iptables -A BADGUYS -s 192.168.11.2    -j DROP
iptables -A BADGUYS -s 192.168.11.3    -j DROP
iptables -A BADGUYS -s 192.168.11.6    -j DROP

I would like something like

iptables -A BADGUYS -m multiip --srclist
[!192.168.10.1,192.168.10.0/24,192.168.11.2,192.168.11.3,192.168.11.6]
- -j DROP

I've had very good success using the ipset patch to iptables.  It allows 
you to use a single iptables rule to refer a named set of ips or nets, 
etc.  The set can then be updated on the fly without having to mess with 
your iptables rules.

hth, :m)

Do you have to use a userspace tool to set the sets of ip addresses?
What is it called?  Where can I get it?

The ipset package provides both a kernel patch and a utility 
conveniently named ipset.
