Hello all,

I am setting up Internet and Email access for one of my clients. This is my first time 
implementing an Internet FireWall. I am looking for any feedback as to what you think 
of my proposed set up. The client wants to use MS Exchange as their Mail server as 
well as MS Proxy and DNS. 

Here is my proposed setup:

                                                                        Private Network
                                                                                      |
                                                                                       
       |
             Router (With Access lists)
                                                                                      |
                                                                                      |
                DMZ--------------------FireWall------Proxy/DNS Servers
      |         |          |  
      |         |          |              
  Exchange    Virus        |
   Server   Scanning       |
             Server        |                                
                           |                                
                           |
                        Router (with access lists)                          
                           |                     
                           |
                           | 
                        Internet                        
                                                                    
                                                        

The FireWall will have a quad ethernet interface with the DMZ and the Internet segment 
having registered IP addresses while the other two segments supporting the proxy/DNS 
and the internal network would use private IP addresses. I will use NAT at the 
FireWall. I am only familiar with FW-1. Is there another FireWall product that you can 
recommend? I am not rushed for time yet, so I have some time to evaluate different 
products.

Thanks a lot for your input in advance.

Saxo
