Figure 3-1 Connection between a computer and the MT882
3.1 When to Configure the MT882
The factory default settings of MT882 have optimized all
functions, and made it run in most network conditions. Usually, the
default setting values can meet basic requirements of users with
simple network topology, and need no change.
If network condition is changed by the modification of security,
scale, line of communication, protocol and topology, for example, a
Huawei Technologies Proprietary
27
demand of particular VPI and VCI, you need to adjust the default
settings accordingly so as to adapt to the changes.
3.2 Configuring IP Settings on Your
Computer
Follow these steps to configure the IP settings:
1) Understand the default IP settings for the MT882: IP
address (192.168.1.1), subnet mask (255.255.255.0).
2) Make sure your computer has the TCP/IP protocol installed
and enabled.
If you have an Ethernet port on your computer, it probably
z
already has TCP/IP protocol installed.
If you are using Windows XP, the TCP/IP is enabled by
z
default for standard installations.
3) Configure the IP address and subnet mask of your
computer. The computer shall work in the same subnet as
that of the MT882. for example, IP address: 192.168.1.100,
subnet mask: 255.255.255.0.
For computers running non-Windows operating systems,
follow the instructions for your OS to configure the IP setting to
occupy the same subnet as MT882.
3.3 Accessing the Web-based Configuration
Manager
Once your PC’s IP settings allow it to access the Web-Based
configuration manager, you can change the factory default settings
to enable the MT882 to connect to Internet.
Huawei Technologies Proprietary
28
3.3.1 Checking for Proxy Service
If the browser software on the computer is configured to use a
proxy server for Internet access, it is necessary to first disable the
proxy connection.
In Internet Explorer, you can check whether a proxy server is
enabled using the following procedures:
1) In the Explorer window, select ToolsÆÆÆÆInternet Options to
display Internet Options dialog box.
2) In the Internet Options dialog box, click the Connections
tab and click on the LAN Settings.
3) Make sure the “Use proxy server” option is not checked. If
it is checked, click on the checked box to deselect the
option and click OK.
3.3.2 Applying the LAN IP Address of MT882
To access the Web-based configuration manager, launch your
Web browser and enter the LAN IP address of the MT882. For the
first access, the default LAN IP address of the MT882 is used. Type
in “http://” followed by the default IP address, “192.168.1.1” in the
address bar of the browser. The URL in the address bar should read:
http://192.168.1.1
.
3.3.3 Inputting the User Name and Password
A new dialog box appears prompting you to input the user name
and password required to access the Web-based configuration
manager.
Huawei Technologies Proprietary
29
Figure 3-2 Enter user name and password
Use the default user name admin and password admin for first
setup. You can change the password once you have opened the
Web-based configuration manager. The user name and password
allows any computer on the same subnet as the MT882 to access
the Web-based configuration manger. And this password can also be
used to Telnet to the device through the Ethernet or Internet
interfaces. To change this password, see 4 Web-Based
Management.
Note:
Do not confuse the user name and password used to access the
Web-based manager with the ADSL account and password needed
for PPP connections to access your ISP’s network.

IP Spoofing: sending packets over the WAN interface
z
using an internal LAN IP address as the source
address
Tear Drop: sending packets that contain overlapping
z
fragments
Smurf and Fraggle: sending packets that use the

WAN or LAN IP broadcast address as the source
address
Land Attack: sending packets that use the same

address as the source and destination address
Ping of Death: illegal IP packet length.
z
Use DoS Protection: click the Allow button to use the
z
following denial of service protections: SYN DoS, ICMP
DoS, Per-host DoS protection
Max TCP Open Handshaking Count: sets the
z
percentage of concurrent IP sessions that can be in the
open state. In ordinary TCP communication, packets are in
the open handshaking state only briefly as a connection is
being initiated; the state changes to active when packets
are being exchanged, or closed when the exchange is
complete. TCP connections in the open handshaking state
can use up the available IP sessions. If the percentage is
exceeded, then the open handshaking sessions will be
closed and replaced with new sessions as they are
initiated.
Max ICMP Count: sets the percentage of concurrent IP
z
sessions that can be used for ICMP messages. If the
percentage is exceeded, then older ICMP IP sessions will
be replaced by new sessions as they are initiated.

Q: Why does my PC fall off line sometimes even with all
LEDs are in normal status?
The following scenarios may cause this problem..
1) Be disconnected by the ISP.
2) Some ISPs will have idle timeout setting to avoid wasting
IP. When the end user connects to the Internet too long
without any packet, the ISP will drop the connection.
Please contact with your ISP about this problem.
3) Some ISPs don’t provide a good quality ADSL signal line.
Therefore, when the ADSL line is unstable, your
connection will be dropped. Try with a telephone and find
the status of your ADSL signal line.
4) If you have contacted the ISP and they promised the
quality of ADSL line, it may be the hardware issue and
please contact your vendor.
Q: When can I use the “Restore Factory Default Setting”
button?
If you changed some setting unconsciously in the Web
Management Interface and you forgot the detailed values that you
modified, please use the “Restore Factory Default Setting” button to
recover the factory default settings.
Q: How many methods can be used to restore the factory
default setting?
