So eth1 could be set up as and the routing would allow specific
connections, much as firewall rules may start with deny all and add specific
connections to allow.

The original query was about assigning the /32 by DHCP - which may support
static routes along with a blizzard of other interesting options not provided by
the usual consumer NAT box. Looks like some good RFC reading ahead.  --Don
