Firewall/NAT

Good morning to everyone, i'm new in this forum FIRST, i do some pologize for my english i doesent speak verry well ^^

Okay, i have a question, i'm going to do a project for my diplome, i will install an Exchange 2010 configuration. So i must use the Mono Wall for that.

I have 2 Address Public for do this, so I have 3 parts on Mono Wall :

Public x.x.x.138 WAN Port on MonoWall

Private 192.168.1.1 LAN Port on MonoWall

x.x.x.139 (Edge Server) and in Mono Wall Dmz Port is Bridged With WAN

So my question is, how i can contact by my LAN to my DMZ ? I think i must configure some with "Proxy ARP" ?

I would not do a bridge.  setup your DMZ interface for something like 192.168.2.1 and 1:1 NAT your x.x.x.139 address to your Exchange server's DMZ address like 192.168.2.200.  also, you need to add a Proxy Arp entry for your x.x.x.139 address and you will also need to add WAN rules to allow traffic to pass to your Exchange server.

Good Luck!

He want, i bridge the Dmz port with the WAN ports, and then my PC in Dmz have a public address and my WAN port Too.

So i need to cominicate From my LAN to my DMZ with the Port 50636 and 50389. But i dont know How...
