Remote Access VPN – PPTP

This chapter introduces PPTP and explains how to implement it.

17.1 Demands

1. One employee in our company may sometimes want to connect back to our corporate network to work on something. His

PC is PC1_1 in LAN_1 instead of DMZ_1 so he cannot directly access the host by simply with virtual server settings. This

causes inconvenience for the employee to work remotely.

17.2 Objectives

1. With PPTP tunneling, emulate the mobile employee as a member in LAN1 after he dials in the corporate network. Then he

can access all computers in LAN_1 just as if he stays in the office covered by LAN1.

17.3 Methods

1. Setup the PPTP server at DFL-1500. Setup the remote PC as the PPTP client. After dialing up to DFL-1, DFL-1 will assign

a private IP which falls in the range of the settings in the PPTP server at DFL-1. Suppose the range is defined as

192.168.40.180 ~ 192.168.40.199, the remote host may get an IP of 192.168.40.180 and logically become a member in

LAN1.
