+This target is only valid in the
+.B nat
+table, in the
+.B POSTROUTING
+chain.  It specifies that the source address of the packet should be
+modified (and all future packets in this connection will also be
+mangled), and rules should cease being examined.  It takes one type
+of option:
+.TP
+.BR "--to-source  " "\fIipaddr\fP[-\fIipaddr\fP][:\fIport\fP-\fIport\fP]"
+which can specify a single new source IP address, an inclusive range
+of IP addresses, and optionally, a port range (which is only valid if
+the rule also specifies
+.B "-p tcp"
+or
+.BR "-p udp" ).
+If no port range is specified, then source ports below 512 will be
+mapped to other ports below 512: those between 512 and 1023 inclusive
+will be mapped to ports below 1024, and other ports will be mapped to
+1024 or above. Where possible, no port alteration will occur.
+.RS
+.PP
+You can add several --to-source options.  If you specify more
+than one source address, either via an address range or multiple
+--to-source options, a simple round-robin (one after another in
+cycle) takes place between these adresses.
