1- install the ISA server after the adsl router and before the switch.

2- put two interface cards in the server 

3- attach one interface with the adsl router ( outside ) and the other to the 
unmanged switch ( inside )

4- assign an IP from your local lan to the inside interface

5- assign any IP of the range that given from the ISP ( after the router nat ) 
to the ouside interface 

6- make ur own rules on the ISA server

        Greetings,
         
        I have attached a basic LAN setup diagram and I would like to pick your 
brains as far as the security is concerned.
         
        My objective is that the In/Outbound traffic must pass thru ISA box 
         
        Base on the attached design I feel that the security is lacking. I have 
downloaded ISA 2006 BETA version...and I want to introduce ISA Server as a 
member of the family to beef-up security. 
         
        How can I make ISA Server 2006 beta play with this basic design, 
bearing in mind that I don't have a static IP address from my ISP. My ADSL is 
dhcp obtaining the IP address from ISP.
         
        I want to run ISA2006 on a separate box completely. 
         
        With many thanks!
         
        Gene Sibbs
