NAME

       exclusion - Exclude a set of hosts from a definition in a shorewall
       configuration file.

SYNOPSIS

       !address-or-range[,address-or-range]...

DESCRIPTION

       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
       lowaddress-highaddress

       No embedded whitespace is allowed.

       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.

EXAMPLES

       Example 1 - All IPv4 addresses except 192.168.3.4
           !192.168.3.4

       Example 2 - All IPv4 addresses except the network 192.168.1.0/24 and
       the host 10.2.3.4
           !192.168.1.0/24,10.1.3.4

       Example 3 - All IPv4 addresses except the range
       192.168.1.3-192.168.1.12 and the network 10.0.0.0/8
           !192.168.1.3-192.168.1.12,10.0.0.0/8

       Example 4 - The network 192.168.1.0/24 except hosts 192.168.1.3 and
       192.168.1.9
           192.168.1.0/24!192.168.1.3,192.168.1.9
