1 NIC 2 networks - 2.May2006 6:11:02 PM

Hi,
Trying to set up a proprietary defined network. Have an ISA server with 2 nics. One has public IP which goes through a router with 4 Nics which supports 2 internal networks and public address. The router has ports open for access from 1 protected lan to DMZ through the public ip connection. See diag below.
                      WWW
                        |
                    router -------internal lan 10.0.0.1/24 (10.0.0.20 - 10.0.0.30 open ports)
                        | public ip 200.0.0.1/30
                       ISA
                        |
                     DMZ 192.168.0.1/24

I want to communicate between servers in internal lan (owa, rpc, smtp, remote desktop, LDAP) and the NATed DMZ. The public ip and connection to internal lan are on the same NIC. What is the best way to set this up (can it be done using ISA 2004)?
Secondly - If I want to put a DNS server in the DMZ - do I need to set it up as a domain in its own right with its external FQDN?
Last - If I have an exchange server (2003) in the internal network do I also need an FE exchange to service OWA or can the ISA2004 firewall also publish the forms based authentication?
Thanks
