Configure a Persistent Connection or a Disconnect Interval

1. On the calling router, open the Routing and Remote Access snap-in.
   
2. In the console tree, under the desired router, click Network Interfaces. Right-click the appropriate demand-dial interface in the details pane, and then click Properties.
   
3. Click the Options tab, and then, under Connection type, do one of the following:
   
   
   • If you want a connection that disconnects, accept the default Demand dial (on-demand) option, and then configure the Idle time before hanging up by using the drop-down list to select, for example, 10 minutes.
     
   • If you want a connection that is always available, select Persistent connection.
     
4. Specify values for Redial attempts and Average redial interval.
