| 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. |
