3.2.1. WAN+4G
Figure 6 WAN+4G
This networking mode has two WAN ports (WAN ports of Ethernet port and 4G ports of M2M network) that can be
connected to WAN simultaneously. The two channels form complementary and backup. At the same time, WAN ports
of Ethernet port are preferred to ensure data fluency and save the traffic of 4G. When WAN ports are abnormal, they
can’t be connected to WAN. The router can also connect to the server through the 4G network port.
In this way, the router doesn’t need any settings to connect to the network line, plug in 4G SIM card, and supply power
to the router. The process of setting up customers is reduced to the greatest extent. Under this networking mode, the
WIFI function of router can also work at the same time to maximize the number of LAN access.
This method is mainly used in the stably network, Such as factory buildings, intelligent buildings, smart cities and other
related industries.

The significance of mandatory portal function lies in the security of LAN network, recodeing illegal acts such as network
attacks using public networks, in addition, it can also be used for advertising purposes, it collects customer information
with the tacit consent of current broadband users, so as to facilitate manufacturers to promote marketing.

3.4.9. VPN Client(PPTP/LTTP/GRE/OPENVPN)
3.4.9.1. 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), 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.

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.
3.4.9.2. L2TP Client
1. L2TP supports multiple authentication (MSCHAPV2, CHAP, EAP, PAP), MPPE encryption, L2TP OVER IPSEC encryption.

192.168.1.1:80 is the web server of routers. If we want to access a device in the LAN from the outside network, we
need to set the mapping from the outside network to the inside network, such as setting the outside network port to
81, the inside network IP 192.168.1.1, and the inside network port to 80.
When we access the 81 port from the WAN port, the access request will be transferred to 192.168.1.1:80.

When work at the net transparent transmission mode, the user can choose to send register package from device to
server. The registration package is designed to enable the server to identify the data source device, or as a password to
obtain authorization for the functions. Registered packets can be sent when a connection between the device and the
server is established, or they can be spliced together at the front of each packet as a data package. The data of the
registration package can be ICCID code, IMEI code, or custom registration data.

When work at net transparent transmission mode, the user can choose to send heartbeat packets to DTU. Heartbeat
packets can be sent to the server side of the network, or to the device port of the serial port.
The main purpose of sending to the network side is to maintain the connection with the server.
In order to reduce communication flow, users can choose to send heartbeat packets (query instructions) to serial device
instead of sending query instructions from server.
