how to configure a router/firewall with no nat

[Elvir Kuric]

Hi, 

I really do not understand why you want to avoid nat?
You probably know that is possible to route ( nat :) 
)
traffic to servers located inside internal network,
and users should not know that, and on specific 
access points ( I mean public ip addresses ) you can
accept all traffic to your servers ( which are inside
safety of internal network )
