IP forwarding of public IP with no NATing

["Kevin Nottelling" <ah_chang_(_at_)_hotmail_(_dot_)_com>]

Hello,

First let me apologize for the newbieness of this question.  I'm trying to 
set up a 2.9 firewall router for machines on public IPs.  I've done it with 
ease on computers with private IPs with an OpenBSD machine handling the 
NATing.

This time, everthing must have public IPs, the external interface and all 
the machines behind the firewall.  I suppose all I'm doing is creating a 
DMZ.  In /etc/sysctl.conf I've already uncommented:
net.inet.ip.forwarding=1

And in rc.conf I have:
ipfilter=YES
ipnat=NO

The ipfilter rules are default right now which pass all.

The internal NIC has a public IP, and connected to a hub.  The protected 
machines have the internal NIC's IP as the default gateway.  So far it's not 
working.

Could someone please tell me what I'm missing?

TIA,

Kevin
