We are planning an extranet at work. We have been thinking about our setup.

There will be:

1. Web Server
2. Extranet SQL Server
3. Intranet Web/SQL Server

My question is: Obviously, the web server will be sat in the DMZ, and the Intranet Web/SQL Server will be on the LAN, but where would you put the Extranet SQL Server so that it can be updated with data from the Intranet Web/SQL Server, and also allow the Web Server to execute stored procedures?

What is the best setup in terms of security?

DMZ
--Web Server
Firewall with non-standard port open (use 1555 for example instead of 1433) and monitoring
--Extranet SQL Server
Firewall with non-standard port and different port than first line
--Intranet Web/SQL Server

You could alternately open up the port directly from 3 to 1, but that would be ill advised. You really ought to have an application tier in the middle to route data.
