-This target is only valid in the
-.B nat
-table, in the
-chain. It should only be used with dynamically assigned IP (dialup)
-connections: if you have a static IP address, you should use the SNAT
-target. Masquerading is equivalent to specifying a mapping to the IP
-address of the interface the packet is going out, but also has the
-effect that connections are
-.I forgotten
-when the interface goes down. This is the correct behavior when the
-next dialup is unlikely to have the same interface address (and hence
-any established connections are lost anyway).

-This specifies a range of source ports to use, overriding the default
-source port-selection heuristics (see above). This is only valid
-if the rule also specifies

-Randomize source port mapping
-If option
-is used then port mapping will be randomized (kernel >= 2.6.21).
