| 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 |
| .BR "--source-ports " "\fI[!] port\fP[,\fIport\fP[,\fIport:port\fP...]]" |
| Match if the source port is one of the given ports. The flag |
| .B --sports |
| is a convenient alias for this option. |
| .TP |
| .BR "--destination-ports " "\fI[!] port\fP[,\fIport\fP[,\fIport:port\fP...]]" |
| Match if the destination port is one of the given ports. The flag |
| .B --dports |
| is a convenient alias for this option. |
| .TP |
| .BR "--ports " "\fI[!] port\fP[,\fIport\fP[,\fIport:port\fP...]]" |
| Match if either the source or destination ports are equal to one of |
| the given ports. |
