Could you provide more details? What do you want to
accomplish? What networks are to be used (dmz, internal
and/or external networks, default routes etc.)
Do you want to forward all IP packets, or do you want
to filter this based on protocol, ports, direction etc.
(eg tcp: http/https/ftp/ssh, udp: dns)
For general info about routing/nat/firewall you might
find the man-pages for ipnat, ipfw, ipf and pf (pfctl)
useful (or confusing, if you are new to this ;-)
If the subject really just means that you want to
use a computer with one NIC that has two external
IPs, you just might to add an alias. See 'man ifconfig'
for this and keep an eye on the _non-conflicting_(!)
netmask.
