<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
|
|
<emphasis>lowaddress</emphasis>-<emphasis>highaddress</emphasis></para>
|
|
|
|
<para>No embedded whitespace is allowed.</para>
|
|
|
|
<para>Exclusion can appear after a list of addresses and/or address
|
|
ranges. In that case, the final list of address is formed by taking the
|
|
first list and then removing the addresses defined in the
|
|
exclusion.</para>
