Well the Title sais it all. I have tried Smoothwall, IPCop, Clarkconnect, Astaro- and none of these have what I need. No mods or anything!! WHAT I NEED, is a firewall OS- that supports:

1) 3 interfaces for LAN, WAN, DMZ

2) Transparent mode on DMZ- ie. basically bridges traffic to the DMZ and ALLOWS there to be public IP's on my webserver in the DMZ.

Someone please help!!!!!!!!!!!!!

What I really need is a Firewall Operating System. Probably Linux Based (with Gui configuration). Open Source/FreeWare- we have exhausted our funds...

You can use ISA.

 My Watchguard X1000 does all that in a hardware box too.

You can use BSD as your base OS; IPtables for configuring the firewalling methods.
But you shall be familier with the *nix, IPtables, some of the routing stuff as well.
A good start will be http://sofi-firewall.sourceforge.net/ or http://www.homenethelp.com/openbsd/bsd-firewall.asp

There is a book i came across some time back."Building Linux and Openbsd Firewalls". This book also helps you to build up.

Use a netscreen with the option to configure it in layer 2.
Or check www.conostix.com very cheap firewalls which are based on open-source. Performance is excellent.

You can use every Firewall that can Route for direct public IP addresses, or else use nat (static or dynamic nat)
