Connecting to a SQL Server database from a Flash program
There are MANY things you will need to consider if you are planning on making your application publicly accessible, some of the common ones are:


If your DB is on your LAN, you need to configure NAT and port forwarding correctly to make it visible on the internet
Permissions need to be set correctly so that your app can access the DB, but random people cannot
Not a very good idea to have an app with its main DB residing on a residential machine
DNS,etc setup since you need to tell the app how to find your computer on the internet
