You'll want to add a second ethernet card to box-1. That card will go
directly to the cable modem. box-1 will be your firewall and router.

Odds are your cable company doesn't want to provide a second IP, or will
charge you for the privilege. Since you mentioned ipmasq already, odds are
good that you just need to change your config from ppp0 to eth1 on box-1,
assuming that eth1 is the new card plugged into the cable modem, and you
can use your RFC1918 addresses just as before.
