<title>Description</title>
<para>Exclusion is used when you wish to exclude one or more addresses
from a definition. An exclaimation point is followed by a comma-separated
list of addresses. The addresses may be single host addresses (e.g.,
192.168.1.4) or they may be network addresses in CIDR format (e.g.,
192.168.1.0/24). If your kernel and iptables include iprange support, you
may also specify ranges of ip addresses of the form
