Check out http://www.gnatbox.com/ They're using a version of freebsd and 
ipf that will do what you are trying to do.  Maybe you should look at 
using ipf.  gnatbox lite is free, but it does not support both a protected 
network and private service network.  The pro version does, but it will 
cost you money.  But if they can do it, then you should be able to do it 
too.

I cannot for the absolute life of me get IPFW to work with three NICS. All 
I
want to do is to:

1) Pass all traffic from internal network (192.168.1.0/24) to go out to 
'net
or to the DMZ.
2) Allow 22,25,53(udp),80,443 traffic in to the DMZ. DMZ is using real IP
addresses (208.53.161.252/30)
3) Allow no traffic from DMZ to flow back into internal network.
3) Block external interface from RFC1918 spoofed addresses

My network is broken up into the following segments:

xl0 - external interface (208.53.161.248/30)
fxp0 - internal interface (192.168.1.0/24)
fxp1 - optional interface (208.53.161.252/30)

I'm using default deny which I feel is safest and compensates for human
error more so than default allow.

I have looked on the web for a DMZ HOWTO and can't find one. Would any of
you have rules that do this? I'm about ready to say fuck it and stick with
the Firebox. Guys, I certainly would appreciate any help with rules on 
this.
I'm tired of fighting with this thing.

Robert
