Description of the illustration vpnusersrestrictacc.gif

This graphic has on the left the label "Untrusted Client" bounded by a dotted line. It is connected to "Firewall" which is further connected to "Load Balancer". To the right is a column of two-sectioned boxes labeled "HTTP Server" and "Proxy plug-in". This column of boxes is labeled "Web Layer" and is surrounded by a dotted line labeled "DMZ" along with Load Balancer. To the right of this column is a column of boxes labeled "Servlet/Object Cluster". Each box contains the labels "JSP", "Servlet", "EJB", and "JDBC". At the bottom right is a Database.

Client points to Load Balancer through the Firewall. The Load Balancer points to the Proxy plug-ins of each of the HTTP Servers with three arrows. The Proxy plug-ins point to each of the boxes in the Servlet/Object Cluster and then to the Database.

The "Trusted Client (internal)" at the bottom points to two boxes in the Servlet/Object Cluster.
