| This module matches IP sets which can be defined by ipset(8). |
| .TP |
| [\fB!\fP] \fB\-\-match\-set\fP \fIsetname\fP \fIflag\fP[\fB,\fP\fIflag\fP]... |
| where flags are the comma separated list of |
| .BR "src" |
| and/or |
| .BR "dst" |
| specifications and there can be no more than six of them. Hence the command |
| .IP |
| iptables \-A FORWARD \-m set \-\-match\-set test src,dst |
| .IP |
| will match packets, for which (if the set type is ipportmap) the source |
| address and destination port pair can be found in the specified set. If |
| the set type of the specified set is single dimension (for example ipmap), |
| then the command will match packets for which the source address can be |
| found in the specified set. |
| .PP |
| The option \fB\-\-match\-set\fP can be replaced by \fB\-\-set\fP if that does |
| not clash with an option of other extensions. |
| .PP |
| Use of -m set requires that ipset kernel support is provided. As standard |
| kernels do not ship this currently, the ipset or Xtables-addons package needs |
| to be installed. |
