The Point-to-Point Tunneling Protocol (PPTP) is a commonly-used method for implementing
VPN and is supported by most clients, including Windows, Mac OS X, Linux, and mobile
devices.
1.
Go to "Control Panel" > "VPN Client".
2.
Click "Add" > "PPTP" to connect a VPN server.
3.
Enter the connection configuration settings, including the profile name, server address
(that you want to connect to), and the username and password of the VPN server.
4.
Choose any of the following authentication mechanisms from the "Authentication" menu
to protect VPN client’s password during authentication:
o
MS-CHAPv2: The password will be encrypted using Microsoft CHAP version 2.
o
MS-CHAP: The password will be encrypted using Microsoft CHAP version 1.
o
PAP: The password will not be encrypted.
o
CHAP: The password will be encrypted using CHAP.
5.
If you choose MS-CHAP or MS-CHAPv2, go to the "Encryption" menu and select an
option:
o
None: The VPN connection will not be encrypted.
o
Medium (AES 40/128 bit): The VPN connection will be encrypted using a 40-bit or
128-bit key.
o
High (AES 256 bit): The VPN connection will be encrypted using a 256-bit key (the
highest-possible level.)
6.
Tick the following checkboxes depending on your configurations:
o
Use the default gateway on remote network: This will allow all packets to be
transferred via the VPN server.
o
Allow other network devices to connect to the VPN through the NAS: This will allow
network devices on the same LAN as the NAS to connect to the same VPN.
o
Reconnect when the VPN connection is lost: This will automatically reconnect to the
VPN server when the connection is lost.
7.
Select "Connect" to start.
Note:
If you check "Use the default gateway on remote network", the default gateway on
your NAS will change to the VPN server’s default gateway.
If you check "Allow other network devices to connect to the VPN through the NAS", the
network device can access the VPN via the NAS. To enable this function, you must change
the default gateway on that other device. Using a Windows PC as an example:
1.
Go to "Control Panel" > "Network an Sharing Center" > "Change adapter settings".
2.
Right click on the connection icon and choose "Properties".
3.
Select "Internet Protocol Version 4 (TCP/IP)" and click "Properties".
