IP assignments, routing and NAT

I want to build up a network with a set of static IP's that my provider
assigned to me. It's a 3-bit subnet of a Class C network address I presume.
So if I let out network (0), gateway (1) and broadcast address (7) there
are five IPs left (e.g. 18.104.22.168 - 22.214.171.124, netmask
So far so good.
- I want to make a number of servers available to the internet using the
different static IPs. They are all connected to the other side of the
firewall and I don't want to use Port Forwarding.
- The computer meant to be the firewall between the servers and the gateway
has only two NICs. It's not possible to extend it.
So I want the servers all reside in a private network (e.g. 192.168.0.0) and
make them available via the static IP's through some kind of static NAT
from the firewall/router. So f.e. all requests from the internet for
126.96.36.199 should be sent to 192.168.0.3, all requests for 188.8.131.52
should be sent to 192.168.0.4 and so on. Is such a configuration possible
(iproute2??). And if, how is such a static 1 to 1 address translation
Hope someone can help me...
