Using SAP MaxDB X Server Behind a Firewall 
SAP MaxDB X Server is the database system's communication server and is located on the database computer. To protect your database, it will usually be located on a computer behind a firewall, for example within your company's LAN (local area network).
Procedure
To enable access to X Server (and thus the database) behind a firewall using a client program such as Database Studio, open the necessary ports in your firewall and restrict access to these ports to only those computers that need to access the database.
