Ⅶ. LTE Settings
1. APN Setting
APN refers to a network access technology, which is a parameter that must be configured when
accessing the Internet through a mobile phone. It determines which access method the mobile phone uses
to access the network. For mobile phone users, there are many types of external networks that can be
accessed, such as the Internet. , WAP website, group internal network, industry-specific private network.
The access range and access mode of different access points are different. APN determines which network
the user’s mobile phone accesses through which access method. APN usually needs to set the access point
name, dialing number, user name and password. And PIN code only needs to be input if it is set. The
system has provided the default APN, so barring special circumstances there is no need to set it.

2. Network Mode
The network mode is divided into automatic selection and manual setting. The system defaults to
automatic selection. Generally, it can be automatically selected without special circumstances. Only when
the network type supported by the SIM card does not match, is manual setting required.
Ⅷ. Network Settings
1. WAN settings
WAN settings can be divided into three modes: dynamic acquisition / static IP / PPPOE dial-up.
Users can select the appropriate mode according to different use conditions.
Dynamic acquisition refers that connect to the WAN port of the machine through the network cable,
and the other end is connected to the LAN port of the upper-level route, and then the device selects
dynamic acquisition to access the Internet (provided that the upper-level route can access the Internet).
The static IP refers that connect to the WAN port of the machine by the network cable, and the other
end is connected to the LAN port of the upper-level route, and then the device can perform related
settings to access the Internet (provided that the upper-level route can access the Internet). The IP address
here should be filled in the upper-level route DHCP. IP address in the server range, and cannot conflict

2. Port Forwarding
Port forwarding refers to port mapping. Port mapping is to map a port of the IP address of the
intranet host to the external network, so that the external network can access to the host to provide
corresponding services. When users access to this port of the IP, the server will automatically request the
mapping to the corresponding machine inside the LAN. Port mapping can be dynamic or static.
