+.SH MATCH EXTENSIONS
+iptables can use extended packet matching modules
+with the \fB\-m\fP or \fB\-\-match\fP
+options, followed by the matching module name; after these, various
+extra command line options become available, depending on the specific
+module. You can specify multiple extended match modules in one line,
+and you can use the \fB\-h\fP or \fB\-\-help\fP
+options after the module has been specified to receive help specific
+to that module.
+.PP
+If the \fB\-p\fP or \fB\-\-protocol\fP was specified and if and only if an
+unknown option is encountered, iptables will try load a match module of the
+same name as the protocol, to try making the option available.

+.SH TARGET EXTENSIONS

+in the standard distribution.
