4.3.4 DHCP Setting
DHCP is short for Dynamic Host Configuration Protocol. It is for
assigning dynamic IP addresses to devices on a network. With
dynamic addressing, a device can have a different IP address every
time it connects to the network. Dynamic addressing simplifies
network administration because the software keeps track of IP
addresses rather than requiring an administration to manage the task.
This means that a new computer can be added to a network without
the hassle of manually assigning it a unique IP address.
1)
DHCP Server
You can configure the DHCP server on the HG520 device for an
efficient dynamic addressing.
On the DHCP Server Settings page, enter the Start IP address, the
End IP address, and the lease time. Single click Submit button to
complete the configuration. Lease time refers to the time frame that
you are allowed to use the assigned IP address. You will have to file
application for a new IP address once the lease time expires.
Click Refresh to renew the DHCP Server settings you just made.

DHCP Relay
DHCP relay is a relay agent for DHCP packets. It is used on a
subnet with DHCP clients to "relay" their requests to a subnet that has
a DHCP server on it. Because DHCP packets can be broadcast, they
will not be routed off of the local subnet. The DHCP relay takes care of
this for the client.
Enter the DHCP Server IP address and click “Submit” to activate
the settings. This function does not work when the PVC setting of NAT
feature is configured in the HG520.

4.3.5 DNS Settings
DNS (Domain Name System) is an Internet service that translates
domain names into IP addresses. Because domain names are
alphabetic, they are easier to remember. The Internet, however, is
based on IP addresses. Every time you use a domain name, therefore,
a DNS service must translate the name into the corresponding IP
address.
Enter the DNS server IP address provided by the ISP on the DNS
Settings page and single click Submit to complete the settings.

4.3.6 NAT
NAT (Network Address Translation) is an Internet standard that
enables a local-area network (LAN) to use one set of IP addresses for
internal traffic and a second set of addresses for external traffic. A NAT
box located where the LAN meets the Internet makes all necessary IP
address translations.
There are three different setting options under the NAT:
z
DMZ
z
NAPT
z
REDIRECT
DMZ (Demilitarized Zone) refers to an isolated area. It is a buffer
area between the non-secure system and the secure system and it is
for the purpose of solving the issue raised when a firewall is installed
and the external networks are blocked to connect to the internal
servers. This demilitarized zone lies between the corporate internal
networks and external networks, in which certain servers, such as
corporate Web servers, FTP servers and corporate bulletin are
located. With the configuration of such DMZ feature, the internal
networks are more securely protected.
Figure 4-15 NAT — DMZ Setting
Huawei Technologies Proprietary
36
NAPT (Network Address and Port Translation) is an extension to
basic NAT, in that many network addresses and their TCP/UDP ports
are translated to a single network address and its TCP/UDP ports.
Please be noted that this feature works only when the PVC with NAT
feature is activated.
Figure 4-16 NAT- NAPT Settings
REDIRECT refers to redirect the packets. Servers redirect
packets to the configured internal IP addresses and ports according to
the IP addresses and TCP/UDP port range of which the packets are
coming from. This feature only works when the PVC settings of NAT
feature are configured.
Single click REDIRECT button as shown in Figure 4-17 and you
will be prompted to the REDIRECT setting page as shown in Figure

Here is the task you want to fulfill: the HTTP service is activated
on the No.80 port of IP address of 192.168.1.2. User communicates
with No.30 port of IP address of 10.132.41.116 via the Internet. When
receiving such communication request, HG520 will redirect the
request to the No.80 port of IP address of 192.168.1.2 and feedback to
No.30 port of IP address of 10.132.41.116 that the request has been
made.
And that’s how you should configure such request: Set the local
port number as 80, local IP as 192.168.1.2, Global Addresses From as
10.132.41.116, Global Addresses To as 10.132.41.126, and the

4.4.4 ACL (Access Control List) Setting
We may configure ACL on HG520 to avoid any unauthorized user
to control the device. ACL keeps the records of the unique
authentication
code,
limit
of
authority, and expiry of such
authentication of the authorized user. With this feature configured,
HG520 will only allow the access of authorized user and avoid any
illegal access.
Enter the IP addresses of the LAN port and select Enable, these
IP addresses will be allowed to access the services listed on the
Service Control List. You can also control the access from the WAN
port to HG520 by repeating the same procedure.
4.4.5 SNTP Setting
NTP (Network Time Protocol) is a time protocol used to
synchronize the time display of different computers in the same
network. SNTP (Simple Network Time Protocol) is a simplified NTP,
which remove the unnecessary internal algorithm in the servers.
Just use the factory default settings of NTP during the selection of
the first and second NTP time server.

4.4.6 IP Filter
IP Filter is a software package that can be used to provide
network address translation (NAT) or firewall services. It restricts the
IP address of a computer or the IP address of a segment to access the
Internet via certain ports.
If the IP filter feature is activated, it allows/rejects the packet from
a specific port of a specific IP address to be forwarded to a local
specific port of a specific IP address. Take Figure 4-27 as example,
the packets from port 100 to port 200 of IP address 10.132.41.120 are
not allowed to be forwarded to local port 100 to port 200 of IP address
192.168.1.100. You can add you own rules based on actual needs.

4.4.7 Multinat Setting
Multi-NAT can be used where you have been allocated multiple
public IP addresses by your ISP. Instead of a many-to-one relationship,
you can have a one-to-one relationship between a public IP address
and an internal/private IP address. This means that you have the
protection of NAT (Network Address Translation) but the PC can be
Huawei Technologies Proprietary
47
addressed directly from the outside world by its fake public IP address,
but still by only opening specific ports to it.
Take Figure 4-28 as example, when internal IP address
192.168.1.56 accesses Internet, Internet will identify this IP address
as 192.168.1.166. Internet user can access the service provided on IP
address 192.168.1.56 via 192.168.1.166.

In most cases, HG520 works with default settings. If you are not
familiar with these parameters, modification is not recommended.
z
AP Isolation: Prevents one wireless client communicating
with another wireless client.
Huawei Technologies Proprietary
68
z
Band: Another term for spectrum used to indicate a
particular set of frequencies. Wireless networking protocols
work in either 2.4GHz (802.11b/g) or the 5 GHz band
(802.11a).
z
Channel: Select the appropriate channel from the provided
list. All devices in your wireless network must use the same
channel in order to function correctly. It is 11 by default.
z
Rate: The range is 1Mbit/s–54Mbit/s. The transmission rate
depends on the speed of your wireless network. You can
select one rate or the default Auto. If you select Auto,
HG520 will automatically obtain the fastest rate.
z
Multicast Rate: In layered multicasting, data is transmitted
in multiple layers. The source encodes the signal in layers,
and a subset of these layers is sent to the receivers,
depending on the receiver requirements, and the congestion
of the path from the source to the receiver. Layered
multicasting is a form of multirate multicasting, since
different receivers in the same multicast group can receive
traffic at different rates.
z
Basic Rate: Select the basic rate that wireless clients
support.
z
Fragmentation Threshold: It is 2346 by default. The range
is 256–2346 bytes.
This value specifies the maximum packet size after data
fragmentation.
If there is a high packet error rate, you can lower the
fragmentation threshold.
Setting the fragmentation too low may result in poor network
performance.
Only slight adjustment of this value is recommended.
Huawei Technologies Proprietary
69
z
RTS Threshold: It is 2347 by default. The range is 0–2347
bytes.
If there is inconsistent data flow, you can make slight
adjustment of this value.
If the network packet is smaller than the RTS threshold,
RTS/CTS will not be enabled.
HG520 sends Request to Send (RTS) to a particular
receiving station and negotiates the transmission of data
frame.
After receiving an RTS, the wireless station responds with a
Clear to Send (CTS) frame to acknowledge the transmission.
Then the transmission begins.
z
DTIM Interval: The range is 1–255 milliseconds. It is the
interval of Delivery Traffic Indication Message (DTIM).
DTIM interval is in countdown mode. It informs clients to
listen to broadcast messages.
When HG520 has stored broadcast information for clients, it
sends the next DTIM according to the DTIM Interval.
Clients receive the beacon and begin to receive the
broadcast message. It is 1 by default.
z
Beacon Interval: The range is 50–2000 milliseconds.
The Beacon Interval is the frequency interval of the beacon.
A beacon is a packet broadcast by HG520 to synchronize
the wireless network. It is 100 by default.
z
XPress™ Technology: this technology can improve the
data transmission rate. By default, it is disabled.
z
54g™ Mode: There are 3 options:
Select 54g Auto for wide compatibility.
Select 54g Performance for the fastest performance.
Huawei Technologies Proprietary
70
Select 54g LRS if you are not familiar with 802.11b
equipment.
z
54g protection: In Auto mode, HG520 can improve
802.11g performance in 802.11g/802.11b mixed network
through RTS/CTS.
The off protection mode can maximize 802.11g throughput
in most cases.
z
Regulatory Mode: Include 802.11d and 802.11h. 802.11d
is a roaming standard that decide what frequency should be
used for data transmission in different countries to ensure
the correct transmission. 802.11h is the evolution of 802.11a
with the new ability of Transmit Power Management
extensions and wireless channel selection so as to comply
with European standards.

Pre-Network Radar Check: To be defined
z
In-Network Radar Check: To be defined
z
TPC Mitigation: Transmit power control is a method of
lowering the transmit power used by a WLAN and it reduces
WLAN interference with satellite services in the 5GHz band.
With the 802.11h amendment to the 802.11a PHY and MAC
layer, TPC mitigation becomes a reality in the 5-GHz band.
Manufacturers are now poised to implement one
standards-based solution to address interference concerns
around the world.
z
Transmit Power: The amount of power used by a radio
transceiver to send the signal out. Transmit power is
generally measured in milliwatts, which you can convert to
dBm. The larger the percentage of transmit power, the
clearer the signal sent.
