SHOREWALL-IPSETS(5)

NAME
ipsets - Specifying the name if an ipset in Shorewall configuration files

SYNOPSIS

+ipsetname

+ipsetname[flag,...]

+[ipsetname,...]

DESCRIPTION

Note: In the above syntax descriptions, the square brackets ("[]") are to be taken literally rather than as meta-characters.

In most places where a network address may be entered, an ipset may be substituted. Set names must be prefixed by the character "+", must start with a letter and may be composed of alphanumeric characters, "-" and "_".

Whether the set is matched against the packet source or destination is determined by which column the set name appears (SOURCE or DEST). For those set types that specify a tuple, two alternative syntaxes are available:
    [number] - Indicates that 'src' or
            'dst' should be repeated number times.
            Example: myset[2].
    [flag,...] where
          flag is src or
          dst. Example: myset[src,dst].

In a SOURCE column, the following pairs are equivalent:

    • +myset[2] and +myset[src,src]

In a DEST column, the following pairs are equivalent:

    • +myset[2] and +myset[dst,dst]

Beginning with Shorewall 4.4.14, multiple source or destination matches may be specified by enclosing the set names within +[...]. The set names need not be prefixed with '+'. When such a list of sets is specified, matching packets must match all of the listed sets.

For information about set lists and exclusion, see shorewall-exclusion[1] (5).

Beginning with Shorewall 4.5.16, you can increment one or more nfacct objects each time a packet matches an ipset. You do that by listing the objects separated by commas within parentheses.

Example:
    +myset[src](myobject)

In that example, when the source address of a packet matches the myset ipset, the myobject nfacct counter will be incremented.

EXAMPLES

+myset

+myset[src]

+myset[2]

+[myset1,myset2[dst]]
