Figure 10-8 Network Topology - The Wireless Router Acts as a PPTP client
In this example, a company’s head office is located in Washington , and its branch office is
located in New York. Now the company wants the head office and branch office to
securely communicate with each other over the Internet.
As shown in Figure 10- 8, we will use PPTP to establish a VPN tunnel, deploy a AC750W
Wireless Router acting as a PPTP client at the branch office, and another VPN appliance
(a UTT VPN gateway is recommended) acting as a PPTP server at the head office. The IP
addresses are as follows:
The AC750W (PPTP Client) at the branch office:
z LAN Subnet: 192.168.1.0/255.255.255.0
z LAN Interface IP Address: 192.168.1.1/255.255.255.0
The VPN appliance (PPTP Server) at the head office:
z LAN Subnet: 192.168.123.0/255.255.255.0
z LAN Interface IP Address: 192.168.123.1/255.255.255.0
