This module matches a set of source or destination ports.  Up to 15
ports can be specified.  A port range (port:port) counts as two
ports.  It can only be used in conjunction with
.B "-p tcp"
or
.BR "-p udp" .
.TP
[\fB!\fP] \fB--source-ports\fP,\fB--sport\fP \fIport\fP[\fB,\fP\fIport\fP|\fB,\fP\fIport\fP\fB:\fP\fIport\fP]...
Match if the source port is one of the given ports.  The flag
.B --sports
is a convenient alias for this option. Multiple ports or port ranges are
separated using a comma, and a port range is specified using a colon.
\fB53,1024:65535\fP would therefore match ports 53 and all from 1024 through
65535.
.TP
[\fB!\fP] \fB--destination-ports\fP,\fB--dport\fP \fIport\fP[\fB,\fP\fIport\fP|\fB,\fP\fIport\fP\fB:\fP\fIport\fP]...
Match if the destination port is one of the given ports.  The flag
.B --dports
is a convenient alias for this option.
.TP
[\fB!\fP] \fB--ports\fP \fIport\fP[\fB,\fP\fIport\fP|\fB,\fP\fIport\fP\fB:\fP\fIport\fP]...
Match if either the source or destination ports are equal to one of
the given ports.
