Would a ether-router/bridge box with 5 ethernet ports work with NAT/ipf to
translate one static IP to four private networks?  i.e.:

208.1.1.1--[NAT/ipf Box]
             | | | |
             | | | +--192.68.1.1---->192.68.1.0/24
             | | +----192.68.2.1---->192.68.2.0/24
             | +------192.68.3.1---->192.68.3.0/24
             +--------192.68.4.1---->192.68.4.0/24

Am concerned about delivering SMTP, HTTP, FTP, etc. to specific servers
for each private network.  I've only dealt with NAT/ipf boxes with only 2
ether cards.  It was pretty straight forward.  But going from one-to-four
is different.
