+ help
+ Masquerading is a special case of NAT: all outgoing connections are
+ changed to seem to come from a particular interface's address, and
+ if the interface goes down, those connections are lost. This is
+ only useful for dialup accounts with dynamic IP address (ie. your IP
+ address will be different on next dialup).
