3.1 Configuring the correct network settings
Before logging to the device through the WEB interface, you must correctly configure the network
computers in network settings.
First, connect your computer to the LAN port of the device, and then set the computer's IP
address.
The first step is to set the computer's TCP/IP. If it has been set correctly, skip this step.
The second step is to set the computer's IP address. You can use either of the following methods:
1. Set the computer's IP address as one of the addresses from 192.168.1.2 - 192.168.1.254, the
subnet mask is 255.255.255.0, and the default gateway is 192.168.1.1 (the LAN IP address of
the device), and the DNS server is the address provided by the local operator.
2. Set the computer's TCP/IP as "Obtain an IP address automatically". After setting, the
built-in DHCP server of the device will automatically assign IP addresses to computers.
The third step is to use the Ping command on your computer to check whether it is connected to
the device. In Start ->Operation, type in cmd, and click <OK> to open the command window.
Type in ping 192.168.1.1.
The following lists two kinds of results of executing the Ping command in the Windows XP

Operator policy: Selects the operator of the interface, with the options as follows: Operator
policy, Telecom, China Unicom and China Mobile respectively.
Working mode: options include NAT and routing mode.
NAT mode: Network address translation. The router working in this mode can convert
the IP address of the Intranet (LAN side) to that of the external network (WAN side).
The router works in this mode by default.
Routing mode: The router working in this mode will not NAT-convert the IP address for
the Intranet (LAN side) to access to the external network (WAN side), and directly looks
up the routing table for forwarding.
Tip:
Both NAT mode and routing mode can take effect to a single line.
MAC address: The MAC address of the related interface, which usually requires no

modification.
Interface mode: Sets the duplex mode and rate for interfaces. Options are: Auto (adaptive),
10M-FD (10M full duplex), 10M-HD (10M half duplex), 100M-FD (100M full duplex),
100M-HD (100M half duplex), 1000M-FD (1000M full duplex, supported by Gigabit
devices). The default is Auto, which is usually not required to be modified, and if there is any
compatibility issue, or the device used does not support auto negotiation function, then the
type of Ethernet negotiation can be set up here.
Tip:
1. When configuring the line, users can select the appropriate operator through "Operator
policy", and the system will generate a corresponding route based on the user's choice, you
can easily achieve the goal that Telecom traffic flows on the Telecom routes while Unicom
traffic flows on the Unicom routes.
2. Generally, it is not recommended to modify the MAC address of interfaces. However, in
some cases, the operator binds the MAC of the device, which results in the failure of the new
network device to dial up successfully, and at this time, the MAC address of the device needs
to be modified as that of the original network device.
2. Static IP access
Figure 6_2 Static IP access
The interface as shown in Figure 6_2 is the configuration interface for fixed IP access.
IP address, subnet mask, gateway address: Static IP address, subnet mask and gateway
address the operator provides to you.

media) are selected, the device will obtain the IP address, subnet mask and gateway address
information through dial-up.
User name and password: The user name and password provided by the operator when it is
conducting services.
Password authentication mode: The way ISP uses to authenticate user names and passwords,
which is EITHER by default. In most areas, PAP is used, and CHAP mode is also used in a
few areas, NONE represents no username and password authentication is to be done,
EITHER means to negotiate with the peer device automatically as to the specific
authentication mode.

connect and hang up.
On-demand dialing: The device will connect automatically when there is Internet traffic
in the Intranet.
Dial-up mode: Selects the PPPoE dial-up mode, which is normal mode by default. If the
dial-up is not successful, try using other modes on the premise of using the correct user name
and password.
Idle time: The time length after there is no traffic of access and before automatic
disconnection, 0 means no automatic disconnection (Unit: minutes).
MTU: Maximum transmission unit, whose default value is 1480 bytes. The device will
automatically negotiate with the peer device. Do not modify it unless in special applications.

6.2 Line combination
This section describes the Network parameter -> Line combination page.
In the line combination configuration, you can quickly configure line combination modes, and
other related parameters, and specify the detection interval, detection number, detection target IP
address and bandwidth of the lines.

Chapter 6 Network parameters
6.2.1 Description of line combination function
1. Line detection mechanism
Regardless of line combination modes, make sure that the network is not interrupted when the line
fails, which require that the device must be able to monitor line status in real time. To this end, we
designed a flexible automatic detection mechanism, and provide a variety of line detection
methods for users to choose, in order to meet the practical application needs.
To facilitate understanding, several related parameters are introduced first.
Detection interval: the time interval of sending inspection packets. One inspection packet is sent
per time, and the default value is 0 seconds. In particular, when the value is 0, it means not to
make line detection.
Detection times: The number of inspection packets sent within each detection cycle.
Destination IP address: The object of detection. The device will send inspection packets to the
pre-designated target to detect if the line is normal.
The following is an introduction of the device's line detection mechanism in two cases: line
normal and line failure.
When a line fails, the detection mechanism is described as follows: The device will send an
inspection packet to the detection target of the line at the specified detection interval. If all the
inspection packets sent have no response within a detection cycle, this line will be deemed to be
failed, and it will be shielded immediately. For example, if the 3 inspection packets that are sent
have no response within a detection cycle, the line is deemed to be failed by default.
When a line is normal, the detection mechanism is described as follows: Similarly, the device will
send an inspection packet to the detection target of the line at the specified detection interval. If
half of the inspection packets or above sent have response within a detection cycle, this line will
be deemed to be normal, and it will be restored. For example, if the 3 inspection packets that are
sent have response within a detection cycle, the line is deemed to be restored by default.
The device allows users to specify Internet lines for some hosts in the Intranet in advance, which
is realized by setting the "Internal starting IP address" and "Internal end IP address" of the line,
and the hosts whose IP addresses are within two address ranges will give priority to the use of the
specified line. For the hosts with the specified Internet line, they can only access to the Internet
through that line when the specified line is normal. However, when the specified line fails, they
will use other normal lines for Internet access.
Tip:Line detection is not enabled, then the "Detection interval" should be set to "0" second.
2. Line combination mode
The device provides 2 line groups: "Main line" group and "Backup line" group. For convenience's
sake, the lines in the "main line" group are collectively known as main line, and the lines in the
