3.5. VPN Client
3.5.1 PPTP Client
We first create VPN Server on the server.
Open the network connection page on the server (remote server) and click File - > New incoming connection.
Then, select Add account, please enter user name, password and other information..
Click Next and check through Internet to connect to this computer.
Then, select "Internet Protocol Version 4" to set the properties of the incoming IP, IP address assignment
select "Specify IP Address", then select "OK" and "Allow Access".
Now we create a VPN server.
Let's talk about the use of VPN Client. We are looking for a computer in the LAN to ensure that it can access
the server above. Then create a new VPN connection.
In the connection box, click "Properties", the tab can set the target address (the address of the VPN server),

USR-G806 software Manual Technical Support: h.usriot.com

security options to select "PPTP protocol", after the point is determined, enter the username, password.
Click the "Connect" button, after the connection is successful, you can see the VPN network card connection,
from grey to bright color, representing the VPN connection has been successfully established.
Next we use the PPTP Client on the router to replace the way of computer dialing.
Assuming that the user has obtained the VPN server address, account and password, we create an interface,
select the PPTP protocol, and write the other parameters in turn.

Figure24 the webpage3 of VPN
Wait a minute or restart the router, when you see the "VPN" interface in the router page, there is a run time (not
0), indicating that the current VPN has been successfully started.
Note:
Currently PPTP supports MPPE encryption and a variety of authentication methods. Specific settings can
be viewed in advanced settings for authentication.
Only MSChapV2 indicates that MPPE encryption is only supported.
MSChapV2 EAP PAP CHAP supports MPPE encryption and multiple authentications.
Other means do not handle, default status, only CHAP authentication by default.
3.5.2 L2TP Client
L2TP is a layer 2 tunneling protocol, similar to PPTP. At present, G806 supports various authentication
methods such as tunnel password authentication, CHAP, etc., supporting encryption methods of MPPE and
pre-shared key encryption methods of L2TP OVER IPSEC.
