+This target is only valid in the
+.B nat
+table, in the
+.B PREROUTING
+and
+.B OUTPUT
+chains, and user-defined chains which are only called from those
+chains.  It redirects the packet to the machine itself by changing the
+destination IP to the primary address of the incoming interface
+(locally-generated packets are mapped to the 127.0.0.1 address).  It
+takes one option:
+.TP
+.BR "--to-ports " "\fIport\fP[-\fIport\fP]"
+This specifies a destination port or range of ports to use: without
+this, the destination port is never altered.  This is only valid
+if the rule also specifies
+.B "-p tcp"
+or
+.BR "-p udp" .
