We have a Windows 2003 web server, a SQL database, and a Sonic Wall. The existing web server is to be replaced. We can see and log into our back office application on the new server when we are looking at local host but when we put it into the DMZ we cannot log into our database. All the ports that allow the old web server to work are open and we have tried swapping the servers out using the same IP addresses but we cant get it to work. Can you help please?
