PPTP-based on-demand branch office

The Dallas branch office is a PPTP-based branch office that uses a router running Windows Server 2003, Standard Edition, to create an on-demand, router-to-router VPN connection with the corporate office router in New York as needed. When the connection is made and is idle for five minutes, the connection is terminated.

To deploy a PPTP, one-way initiated, on-demand, router-to-router VPN connection to the corporate office based on the settings configured in Common configuration for the VPN server and On-Demand Branch Office, the following settings are configured on the Dallas router.
