Web app

Hi

We would like to set a web app externally on DMZ. The database will be on the internal lan. We would like to secure our database transactions. It will be build in c# and the database is MS SQL 2008.

Which is the most secure and recommended way to talk to the database?

Thanks

Make SQL communicate thru a port other than 1433, make an exception on the firewall for that port and let the application communicate thru that port
