Hello

I have a rather strange setup I need to implement can some one tell me 
will this work, and how best to implement it.


Internet
    |
    |
MonoWall1
    |
    |-------------------DMZ Servers with Real World IP's X.X.X.X /27
    |
Mono Wall2
    |
    |
Private LAN(192.168.1.0)


MonoWall1 (WAN) = A realworld IP X.X.X.X /30
MonoWall1 (LAN) = A realworld IP X.X.X.X/27

DMZ Servers = realworld IP's X.X.X.X/27

MonoWall2 (WAN) = A realworld IP X.X.X.X /27
MonoWall2 (LAN) = 192.168.1.1

I have servers/services in the private LAN that hosts on the internet 
need to access.

I need to make sure that hosts in the Private LAN can access the 
internet (PING WEB SMTP etc..)

I also need to make sure hosts on the internet can access the DMZ servers.

Will Mono allow me to do this.

I will also eventually be wanting to use IPSEC tunnels from MonoWall1 to 
remote sites, will I be able to access these sites from the Private LAN 
and the DMZ?

If someone could could clue me up on what the issues are involved here 
that would be great. My biggest confusion is will I need NAT to the DMZ 
or not, and if not how do I turn off NAT for the DMZ.

Thanks
Mark
