So eth1 could be set up as 22.214.171.124/32 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
