Strictly speaking, what you want is RFC 1631 Name Address Translation
(NAT). Alas Linux masq does not do NAT, it is on the wish list. In
the meantime, grab the TIS FireWall ToolKit (fwtk) from
http://www.tis.com/docs/products/fwtk/index.html and use whichever
plugins suit your requirements, but watch their licencing agreement.
