VPN Settings
VPNs (Virtual Private Networking) provide secure communication between
two separate networks without using a dedicated leased line. In order to
achieve this functionality, a secure tunnel must be built between the two sites
for secure communication over the Internet. The SA supports the most
popular protocol - PPTP. PPTP (Point-to-Point Tunneling Protocol),
described in RFC 2637 is a PPP-specific protocol proposed by Microsoft. The
SA implements a PPTP server. The remote user can connect to the PPTP
server and access a local host behind the PPTP server. When you select the
VPN item in left menu of the web page, PPTP configuration options will
appear. Please refer to the corresponding section for these configurations.
•PPTP Settings
For most companies, the PPTP server creates a secure connection that a
remote user can access a host within the company. The remote user has
to run a PPTP client and connect to the PPTP server. The PPTP server
has to validate the remote user as being in the User List in section 9.1.
The server certifies the PPTP client with a username and password. After
passing the certification, the server will assign a private IP address to the
client. The remote user will be treated like a member of the LAN and can
access the local hosts inside the company. Please refer to Appendix A
for more details about configuring a PPTP VPN connection. To run the
PPTP server on the company side, please follow the steps below:
1. In PPTP Settings page: Select the Enable button in PPTP Server
field. (Figure 6.1)
2. Enter the private IP address of the server in Server IP Address field.
3. Enter the Client IP Range. The server will assign the IP to each client
within the range.
4. Click the apply button.
