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
