1 This target is only valid in the
7 chains, and user-defined chains which are only called from those
8 chains. It redirects the packet to the machine itself by changing the
9 destination IP to the primary address of the incoming interface
10 (locally-generated packets are mapped to the localhost address,
11 127.0.0.1 for IPv4 and ::1 for IPv6).
13 \fB\-\-to\-ports\fP \fIport\fP[\fB\-\fP\fIport\fP]
14 This specifies a destination port or range of ports to use: without
15 this, the destination port is never altered. This is only valid
16 if the rule also specifies one of the following protocols:
17 \fBtcp\fP, \fBudp\fP, \fBdccp\fP or \fBsctp\fP.
22 is used then port mapping will be randomized (kernel >= 2.6.22).
24 IPv6 support available starting Linux kernels >= 3.7.
