1 This module matches a set of source or destination ports. Up to 15 2 ports can be specified. A port range (port:port) counts as two 3 ports. It can only be used in conjunction with one of the 4 following protocols: 5 \fBtcp\fP, \fBudp\fP, \fBudplite\fP, \fBdccp\fP and \fBsctp\fP. 6 .TP 7 [\fB!\fP] \fB\-\-source\-ports\fP,\fB\-\-sports\fP \fIport\fP[\fB,\fP\fIport\fP|\fB,\fP\fIport\fP\fB:\fP\fIport\fP]... 8 Match if the source port is one of the given ports. The flag 9 \fB\-\-sports\fP 10 is a convenient alias for this option. Multiple ports or port ranges are 11 separated using a comma, and a port range is specified using a colon. 12 \fB53,1024:65535\fP would therefore match ports 53 and all from 1024 through 13 65535. 14 .TP 15 [\fB!\fP] \fB\-\-destination\-ports\fP,\fB\-\-dports\fP \fIport\fP[\fB,\fP\fIport\fP|\fB,\fP\fIport\fP\fB:\fP\fIport\fP]... 16 Match if the destination port is one of the given ports. The flag 17 \fB\-\-dports\fP 18 is a convenient alias for this option. 19 .TP 20 [\fB!\fP] \fB\-\-ports\fP \fIport\fP[\fB,\fP\fIport\fP|\fB,\fP\fIport\fP\fB:\fP\fIport\fP]... 21 Match if either the source or destination ports are equal to one of 22 the given ports. 23
