Microsoft SQL Server: usefull TCP and UDP ports

If you would have to open only 2 ports in your firewall for Microsoft SQL Server to work, it would be:

- inbound TCP 1433: Authenticated SQL inbound connections
- inbound UDP 1434: Unauthenticated server browser queries

For more information, please check Configure the Firewall to allow SQL Server access article on Technet.
