4.2 Load Balancing
This section describes the Network > Load Balancing page. When using multiple
Internet connections, you can configure load balancing related parameters, such as
load balancing mode, detection interval, retry times, and ID binding, and so on.
4.2.1 Internet Connection Detection Mechanism
When using multiple Internet connections, the Device should have the ability to
real-time monitor each Internet connection to ensure the network will not be
interrupted even a connection is faulty. To this end, we design flexible automatic
detection mechanism on the Device and provide multiple detection methods to meet
the actual requirements.
For the sake of convenience, we firstly introduce several parameters.
● Detection T ar get IP: The IP addres s o f a target device. The Device will monitor an
Internet connection by sending the detection packets to the specified target IP
address.
● Detection Interval: The time interval at which the Device periodically sends
detection packets, one packet at a time. Especially, if you don’t want to monitor an
http://www.uttglobal.com Page 25
UTT Technologies Network Menu
Internet connection, please set it as 0.
● Retry Times: The number of retries per detection period.
For a normal Internet connection and a faulty Internet connection, the detection
mechanisms are different.
For a faulty normal Internet connection, the detection mechanism is as follows: The
Device periodically sends a detection packet at th e speci fied time inte rv al t o the target
IP address. Once no response packet received during a detection period, the Device
will consider that the connection is faulty and shield it immediately. For example, by
default, if the Device has sent three detection packets but not received any response
packet during a detection period, it will consider that the connection is faulty.
For a normal Internet connection, the detection mechanism is as follows: Similarly, the
Device also periodically sends a detection packet at the specified time interval to the
target IP address. Once more than half of the response packets received during a
detection period, the Device will consider that the connection is back to normal and
enable it immediately. For example, by default, if the Device has sent three detection
packets and received two packets during a detection period, it will consider that the
connection is back to normal.
Note: If you don’t want to monitor an Internet connection, please set the value of
Detection Interval as 0.
4.2.2 Global Settings
The Device provides two connection groups: primary connection group and backup
connection group. An Internet connection belonging to the primary connection group
is a primary connection while an Internet connection belonging to the backup
connection group is a backup connection. By default, all the Internet connections are
primary connections. It allows you to divide one or more connections into the backup
connection group.
The Device provides two load balancing modes:
Balancing.
If you choose to use
primary connections. The operation principle is as follows:
1) If all the Internet connections are normal, the LAN users will use these
connections to access the Internet.
Full Load Balancing, all the Internet connections are used as
Full Load Balancing and Partial Load
2) If an Internet connection is faulty, the Device will shield it immediately, and the
traffic through the faulty connection will be distributed to other normal conne ctions
automatically.
http://www.uttglobal.com Page 26
UTT Technologies Network Menu
3) Once the faulty connection is back to normal, the Dev ice will enable it immediately,
and the traffic will be redistributed automatically.
If you choose to use Partial Load Balancing, some Internet connections are used as
primary connections, and others are used as backup connections. The operation
principle is as follows:
1) As long as one or more primary connections are normal, the LAN users will use
the primary connection(s) to access the Internet. In this case, if there is more than
one primary connection, the Device will control and balance the traffic among
these connections.
2) If all the primary connections are faulty, it will automatically switch to the backup
connection(s) to let the LAN users use them to access the Internet. In this case, if
there is more than one backup connection, the Device will control and balance
the traffic among these connections.
3) Once one or more faulty primary connections are back to normal, it will
automatically switch back to the primary connection(s).
Note: During connections switching, some user appl ications (such as some online
games) may be interrupted unexpectedly due to the nature of TCP connection.
UTT Technologies Co., Ltd. will not bear all the losses and legal
caused by it.

4.2.5 Identity Binding
When using multiple Internet connections, the same application will be assigned to
the different connections, thus some applications (such as online banking, QQ, etc.)
cannot be used normally due to the identity change. We provide ID binding feature to
solve this problem: After you enable Identity Binding, the Device will assign the same
application to the same Internet connection. For example, when a LAN user logs in to
an online banking system, if the first session is assigned to the WAN2 Internet
connection, henceforth all the subsequent NAT sessions of the online banking
application will be assigned to the WAN2 connection until the user logs out.
Figure 4-12 Identity Binding
Enable ID Binding: If selected, you will enable ID binding feature for some
applications such as online banking, QQ, etc.

Note:
1) You can assign two IP addresses to the Device’s LAN interface to connect two
subnets. The hosts on the two subnets can communicate with each other.
2) If you have changed the LAN IP address and saved the change, you should use
the new IP address to re-login to the Device. And the default gateway of each
LAN host should be changed to this new IP address, thus the LAN hosts can
access the Device and Internet.

4.4 DHCP Server
The Dynamic Host Configuration Protocol (DHCP) provides a framework for passing
configuration information to hosts on a TCP/IP network. DHCP allows a host to be
configured automatically, eliminating the need for intervention by a network
administrator. The Dev ice can act as a DHCP serv er to assign network addresses an d
deliver other TCP/IP configuration parameters (such as gateway IP address, DNS
server IP address, etc.) to the LAN hosts.
4.4.1 DHCP Server Settings
The DHCP server assigns an IP address to a requesting client from a DHCP address
pool, which also can be configured to provide other TCP/IP configuration parameters
to the client, such as the DNS Server, gateway IP address, etc.
Figure 4-14 DHCP Server Settings
http://www.uttglobal.com Page 32
UTT Technologies Network Menu
Enable DHCP Server: Select to enable DHCP server.
Start and End IP Address: Specify the range of IP addresses assigned to DHCP
clients. The range of IP addresses must be on the same subnet as the LAN
interface of the Device, and cannot include the IP address of the LAN interface.
Subnet Mask: The subnet mask address assigned by the DHCP server to the
intranet computers automatically. This subnet mask must match the subnet mask
of the LAN interface.
Gateway IP: Specify the gatew ay IP address assigned by the DHCP server to th e
intranet computers automatically. This gateway IP address must mat ch the
gateway IP address of the LAN interface.
Lease Time: The leasing time for the network computers to obtain the IP address
assigned by the Device (Unit: Seconds).
Primary DNS Server: The primary DNS server IP address assigned by the DHCP
server to the Intranet computers automatically.
Secondary DNS Server: The secondary DNS server IP address assigned by the
DHCP server to the Intranet computers automatically.
Option 43: By modifying the variable length fields of option 43 attribute in the
DHCP protocol packets which is used to carry the IP address of AC, AP analyze
the AC address carried by option 43 to discover AC. The available options are
Disable, HEX Length, ASCII Length, and Customized.
AC Address: The IP address of AC.
Enable DNS Proxy: Select to enable DNS Proxy. When acting as a DNS proxy,
the Device listens for incoming DNS requests on the LAN interface, relays the
DNS requests to the current public network DNS servers, and replies as a DNS
resolver to the requesting LAN hosts.
ISP DNS Server 1 or ISP DNS Server 2: Specify the IP address of ISP’s DNS
server that is available to a DHCP client.
Note:
1) If the DHCP Server is enabled, the LAN computer could obtain an IP address and
other TCP/IP parameters from the Device’s built-in DHCP server aft er setting the
way of computer’s getting IP address as "obtain an IP address automatically".
2) If the DNS proxy is enabled on the Device, in order to use DNS proxy service
normally, the LAN hosts’ primary DNS server needs to be set same to the
Device’s LAN IP address. Note: If the DHCP server is also enabled on the Device,
the Device will assign its LAN IP address as the primary DNS server address to
the LAN hosts automatically.
3) To ensure that the DNS proxy works well, you should at least specify the primary
http://www.uttglobal.com Page 33
UTT Technologies Network Menu
DNS server provided by your ISP on the Device. It is obvious that you can specify
the secondary DNS server provided by your ISP.
4) The Device can act as a DNS proxy server to all LAN users; this greatly simplifies
the LAN hosts setup. For example, there is a LAN DNS proxy server on which a
DNS proxy software is installed (e.g., Wingate), and the LAN users take this
server’s IP address as the primary DNS server address. Now, the Device will be
used as a new gateway for the LAN hosts. In this case, in order to use DN S prox y
service normally, the administrator only need change the Device’s LAN IP
address to the old proxy DNS server’s IP address, and enable DNS proxy on the
Device, without modifying the LAN hosts’ related settings.
4.4.2 Static DHCP
This section describes the static DHCP list and the way to configure a static DHCP.
Using the DHCP Server to automatically configure TCP/IP properties for the LAN
computers is very convenient, but it can cause a computer to be assigned with
different IP address at different times. Some Intranet computers may need a fixed IP
address; in this case, the static DHCP function is required, to bind the computer's MAC
address with an IP address. As shown in Figure 4-15, when a computer with
00E06108A443 as MAC address requests the IP address from the DHCP server, the
DHCP server will find a corresponding fixed IP address (192.168.1.101) based on its
MAC address and assign it to the computer.
4.4.2.1 Static DHCP List
You can add, view, modify and delete static DHCP entries on the Network > DHCP
Server > Static DHCP page.
Figure 4-15 Static DHCP List
http://www.uttglobal.com Page 34

IP Address: Specify the reserved IP address, which must be the valid IP address
within the range of IP addresses assigned by the DHCP server.
MAC Address: Specify the MAC address of the computer to use this reserved IP
address in a fixed way.
Note:
1) After the setting is successful, the Device will assign the preset IP address for the
specified computer in a fixed way.
2) The assigned IP addresses must be within the range provided by the DHCP
server.
4.4.3 DHCP Auto Binding
If the hosts change frequently on the local area network, it is very troublesome to
configure static DHCP entries manually. And it will cause some user s who c an’t acce ss
the Device and Internet. To deal with these issues, the Device provides DHCP
auto-binding feature.
Once the DHCP auto binding is enabled, the Device will immediately scan the LAN to
detect active hosts connected to the Device, learn dynamic ARP information and bind
the related valid IP and MAC address as a static DHCP entry.
http://www.uttglobal.com Page 35
UTT Technologies Network Menu
Figure 4-17 DHCP Auto Binding
Enable DHCP Auto Binding: If selected, once a LAN host obtains an IP address
from the Device that acts as a DHCP server, the Device will immediately bind the
host’s IP and MAC address as a static DHCP entry.
Enable DHCP Auto Deleting: If selected, the Device will automatically delete the
static DHCP entry when the corresponding host releases the IP address
initiatively or its lease time expires.
4.4.4 DHCP Client List
When acting as a DHCP client, the Device can dynamically obtain an IP address and
other TCP/IP configuration parameters from a DHCP server. The information of those
DHCP clients who have obtained an IP address and other TCP/IP configuration
parameters will be display in the
DHCP server assigns the IP address of 192.168.1.100 in the address pool to the
network computers whose MAC address is 74:D4:35:47:26:74, and the rest of the
time for the computer to lease this IP address is 3,574 seconds.

Dynamic Domain Name Service (DDNS) is a service used to map a domain name
which never changes to a dynamic IP address which may change quite often. For
example, if you have applied PPPoE connection with dynamically assigned IP
address from the ISP, you can use DDNS to allow the external computers to access
the Device by a static domain name.
In order to use DDNS service, you need to register an account with a DDNS provider.
Each DDNS provider offers its own specific network services. The DDNS service
provider reserves the right to change, suspend or terminate your use of some or all
network services at any time for any reason. The DDNS service providers supported
by UTT Technologies currently provide free DDNS services, but they may charge for
the DDNS services in the future. In this case, UTT Technologies will notify you as
soon as possible; if you refuse to pay for the services, you will no longer be able to
use them. During the free phase, UTT Technologies does not guarantee that the
DDNS services can meet your requirements and will be uninterrupted, and UTT does
not guarantee the timeliness, security and accuracy of the services.

1) If your ISP assigns a private IP address (192.168.x.x, 10.x.x.x, or 172.16.x.x)
instead of a public IP address to the Device, DDNS will not work.
2) DDNS feature can help you implement VPN tunnels using dynamic IP addresses
on the Device.
4.6 UPnP
The Universal Plug and Play (UPnP) is an architecture that implements zero
configuration networking, that is, it provides automatic IP configuration and dynamic
discovery of the UPnP compatible devices from various vendors. A UPnP compatible
device can dynamically join a network, obtain an IP address, announce its name,
convey its capabilities upon request, and learn about the presence and capabilities of
other devices on the network.
The Device can implement NAT traversal by enabling UPnP. When you enable UPnP,
the Device allows any LAN UPnP-enabled device to perform a variety of actions,
including retrieving the public IP address, enumerate existing port mappings, and add
or remove port mappings. By adding a port mapping, a UPnP-enabled device opens
the related service ports on the Device to allow the Internet hosts access. Windows
Messenger is an example of an application that supports NAT traversal and UPnP.
The Device provides
rules established using UPnP. You can view each port forwarding
information in the list, which includes internal IP address, internal port, protocol,
remote IP address, external port, and description.

5.4 Advanced
On the Wireless > Advanced page, you can setup advanced parameters of the
wireless mode, such as RTS Threshold, Fragmentation Threshold, and so on. In most
case, you can keep it as the default value but you have special needs.
Figure 5-10 Advanced Wireless Settings
RTS Threshold: Specify the value of RTS Threshold. Value range is 1~2347 bytes,
and the default is 2347 bytes. Typically, sending RTS/CTS frames does not occur
unless the packet size exceeds this threshold. If the packet size that the node
wants to transmit is larger than the threshold, the RTS/CTS handshake gets
triggered. The process of transmitting data is as following :
1) Device A (for example) initiates the process by sending a R equest to Sent
(RTS) to Device B (for example).
2) Device B replies with a Clear To Send (CTS).
3) After receiving CTS, Device A sends data.
RTS/CTS is the optional mechanism used by the 802.11 wireless networking
http://www.uttglobal.com Page 53
UTT Technologies Wireless Menu
protocol to reduce frame collisions introduced by the hidden node problem. The
value of RTS Threshold should be set reasonably. The smaller the value is, the
higher the frequency of the Device sends RTS frames are. Obviously, it will
influence the throughput, but it will be faster recovering from interrupt and data
collision.
Fragmentation Threshold: Specify the maximum length of wireless data packet
allowed to transmit on MAC layer. When the length of Data frames exceeds this
value, they will automatically be segmented into multiple data frames, and then
transmitted again. If the fragmentation transmission is interrupted, only the parts
that are not sent successfully need to be sent, and the throughput of
fragmentation packets is generally low. Value range is 256~2346 bytes, and the
default is 2346 bytes.
Beacon Interval: The Device synchronizes with the wireless network by
periodically broadcasting a beacon frame. This parameter is used to specify the
transmission interval of beacon frames. Value range is 20~999 milliseconds, and
the default is 100 milliseconds.
DTIM Interval: A Delivery Traffic Indication Map (DTIM) period value is a number
that determines how often a beacon frame includes a Delivery Traffic Indication
Message, and this number is included in each beacon frame. A DTIM is included
in beacon frames, according to the DTIM period, to indicate to the client devices
whether the access point has buffered broadcast and/or multicast data waiting for
them. Following a beacon frame that includes a DTIM, the access point will
release the buffered broadcast and/or multicast data if any exists. Its use range is
1 ~ 255 and its default value is 1.
Enable Short Preamble: If selected, it will use Short Preamble. Short
Preamble can improve the utilization of wireless channel to realize high priority
transmission bandwidth. If not, it will use long preamble. Which can ensure
compatibilities with some old 802.11b devices that require the long preamble, but
it will slightly reduce throughput at high data rate.
Enable WMM: WMM (Wi-Fi Multimedia) is a subset of the 802.11e standard.
WMM allows wireless traffic to have a priority range based on the data type.
Time-sensitive information, such as video or audio, will have a higher priority than
the normal traffic. To use the WMM function properly, wireless clients must also
support WMM.

7.1 NAT&DMZ
This chapter describes how to configure and use NAT features, including port
forwarding, DMZ hosts, and NAT rule.
7.1.1 Port Forwarding
Port forwarding can be used to set up public services on your network. When users
from the Internet make certain requests on your network, the Device can forward
those requests to computers equipped to handle the requests. For example, if you set
the port number 21 (FTP) to be forwarded to IP address 192.168.1.2, then all the
related requests from outside users will be forwarded to 192.168.1.2.
7.1.1.1 Port Forwarding List
On the Advanced > NAT & DMZ > Port Forwarding page, you can setup some port
forwarding rules.

external port is 2001 and the port count is 10, then the internal port range is from
21 to 30, and the external port range is from 2001 to 2010.
Bind to: Select the NAT rule to which this port forwarding rule is bound. The port
forwarding rule will use the WAN interface’s IP address as the external IP
address.
Note: The system will automatically create some port forwarding rules. You
cannot modify or delete them.
7.1.1.3 Examples of Port Forwarding
7.1.1.3.1 Example One
An organization wants a LAN server (IP Addr ess: 192.168.16.88) to open Syslog
service (Protocol: UDP; Port: 514) to the outside users. And the Device will use 2514
as the external port and the WAN1 IP address (200.200.200.88 in this example) as
the external IP address. Then all the requests for Syslog from outside users to
200.200.200.88:2514 will be forwarded to 192.168.16.88:514.
The following figure shows the detailed settings.
Figure 7-3 Port Forwarding settings - Example One
7.1.1.3.2 Example Two
An organization wants a LAN server (IP Addr ess: 192.168.16.100) to open ftp service
(Protocol: TCP; Port: 20, 21) to the outside users. And the Device will use 2020 and
2021 as the external ports and the WAN2 IP address (200.200.201.18 in this example)
as the external IP address. As the ftp service uses two ports, so we need to set the

Port Count to 2. Then all the requests for ftp from outside users to
200.200.201.18:2020 or 200.200.201.18:2021 will be forwarded to 192.168.16.100:20
or 192.168.16.100:21.
The following figure shows the detailed settings.
Figure 7-4 Port Forwarding Settings - Example Two
7.1.1.3.3 Example Three
An organization obtains eight public IP addresses (from 218.1.21.0/29 to
218.1.21.7/29) from the ISP. Therein, 218.1.21.1/29 is used as the Internet
connection’s gateway IP address, 218.1.21.2/29 is used as the Device’s WAN1
interface’s IP address.
The organization wants a LAN server (IP Address: 192.168.16.88) to open SMTP
service (Protocol: TCP; Port: 25) to the outside u sers. And the Device w ill use 2025 as

7.1.2 NAT Rule
7.1.2.1 Introduction to NAT
The NAT (Network Address Translation) is an Internet standard that is used to map
one IP address space (i.e., Intranet) to another IP address space (i.e., Internet). The
NAT is designed to alleviate the shortage of IP addresses, that is, it allows all the LAN
hosts to share a single or a small group of IP addresses: On the Internet, there is only
a single device using a single or a small group of public IP addresses; but the LAN
hosts can use any range of private IP addresses, and these IP addresses are not
visible from the Internet. As the internal network can be effectively isolated from the
outside world, the NAT can also provide the benefit of network security assurance.
The Device provides flexible NAT features, and the following sections will describe
them in detail.
To ensure that NAT operates properly, the Device uses and maintains two address
spaces:
● Internal IP address: It indicates the IP address that is assigned to a LAN host by
the administrator. It is usually a private IP address.
NAT Address Space Definitions
● External IP address: It indicates the IP address that is assigned to the Device’s
Internet connection by the ISP. It is a legal public IP address that can represent
one or more internal IP addresses to the outside world.
http://www.uttglobal.com Page 68
UTT Technologies Advanced Menu
7.1.2.3 NA T Types
The Device provides two types of NAT: One2One and EasyIP.
One2One (One to One): It indicates static network address translation. It is always
referred to as Basic NAT, which provides a one to one mapping between an internal
and an external IP address. In this type of NAT, IP address need be changed, but port
needn’t.
One to One NAT can be used to allow the outside users to access a LAN server: In
the local network, the LAN server still uses the private IP address, which is provi ded to
the LAN hosts to access; and on the Internet, the Device will assign an external IP
address to the local server, then the outside users can use this external IP address to
access the server through the Device.
EasyIP: It indicates network address and port translation (NAPT). Since it is the most
common type of NAT, it is often s i mply ref erred to as N AT. NAPT provides
many-to-one mappings between multiple internal IP addresses and a single external
IP address, that is, these multiple internal IP addresses will be translated to the same
external IP address. In this type of NAT, to avoid ambiguity in the handling of returned
packets, it must dynamically assign a TCP/UDP port to an outgoing session and
change the packets’ source port to the assigned port before forwarding them. Besides,
the Device must maintain a translation table so that return packets can be correctly
translated back.
When you obtain multiple public IP addresses from your ISP, you can create more
than one NAT rule for each type of NAT. In an actual network environment, different
types of NAT rules are often used together.

Bind to: Specify an Internet connection to which the NAT rule is bound. The LAN
hosts that match the NAT rule will access the Internet through this Internet
connection.
Note:
1) When creating a One2One NAT rule, you should set the Sta rt External IP Address,
and the number of the external IP addresses is the same as the number of
internal IP addresses, which is determined by the
End Internal IP Address. For example, if the St art Internal IP Address is
192.168.16.6,
Address is 200.200.200.116, then 192.168.16.6, 192.168.16.7, and 192.168.16.8
will be mapped to 200.200.200.116, 200.200.200.117, and 200.200.200.118

1) Requirements
In this example, a business has a single s tatic IP Internet connection and obtains eigh t
public IP addresses (from 202.1.1.128/29 to 202.1.1.1.135/29) from the ISP. Therein,
202.1.1.129/29 is used as the Internet connection’s gateway IP address,
202.1.1.130/2 is used as the Device’s WAN1 interface’s IP address. Note that
202.1.1.128/29 and 202.1.1.1.135/29 cannot be used as they are the subnet number
and broadcast address respectively.
http://www.uttglobal.com Page 71
UTT Technologies Advanced Menu
Figure 7-9 Network Topology for One2One NAT Rule Configuration Example
The business employees will share a single public IP address of 202.1.1.130/29 to
access the Internet. The LAN’s subnet number is 192.168.16.0, and subnet mask is
255.255.255.0. And the business wants to use the remaining four public IP addresses
(from 202.1.1.131/29 to 202.1.1.134/29) to create a
One2One rule for the four local
servers, then the outside users can use these public addresses to access the local
servers through the Device. The four local servers IP addresses are from
192.168.16.200/24 to 192.168.16.203/24, which are mapped to 202.1.1.131/29,
202.1.1.132/29, 202.1.1.133/29, 202.1.1.134/29 respectively.
2) Analysis
Firstly we need to configure a static IP Internet connection on the WAN1 interface in
the
Basic > WAN page or through the Setup Wizard. After you have configured the
Internet connection, the Device will automatically create a related system reserved
NAT rule, and also enable NAT.
Secondly, we need to create a One2One NAT rule for the four local servers. After you
have configured this rule, the Device will automatically create the related static route.
3) Configuration Procedure
The configuration steps are as following:
Step 1 Go to the Advanced > NAT & DMZ > NAT Rule page, and click the Add
button to go to the setup page.
Step 2 Enter the name of this NAT rule entry in the Rule name text box and select

7.1.2.6.2 Example for Configuring EasyIP NAT Rule
(1) Requirements
In this example, an Internet cafe has a single Internet connection and obtains eight
public IP addresses (from 218.1.21.0/29 to 218.1.21.7/29) from the ISP. Therein,
218.1.21.1/29 is used as the Internet connection’s gateway IP address, 218.1.21.2/29
is used as the Device’s WAN1 interface’s IP address. Note that 218.1.21.0/29 and
218.1.21.7/29 cannot be used as they are the subnet number and broadcast address
respectively.
The administrator wants the hosts in the online game area (its address range is from
192.168.16.10/24 to 192.168.16.100/24) to use 218.1.21.3/29 to access the Internet.

7.1.3 DMZ
The DMZ (Demilitarized Zone) feature allows one local computer to be exposed to the
Internet for the use of a special service such as an online game or video con ferencing.
When receiving the requests initiated by outside users, the Device will directly forward
these requests to the specified DMZ host.
Figure 7-12 DMZ
Enable DMZ: Select to enable DMZ Host.
http://www.uttglobal.com Page 74
UTT Technologies Advanced Menu
DMZ Host IP Address: Specify the private IP address of the DMZ host.
Note:
The computer designated as the DMZ host will lose firewall protection provided by the
Device. As the DMZ host is exposed to many exploits from the Internet, it may be
used to attack your network.
7.1.4 Priorities for Port Forwarding and DMZ Host
The port forwarding has higher priority than the DMZ host. When receiving a request
packet initiated by an outside user, the Device will firstly search the
List to find out if there is a port forwarding rule matching the destination IP address
and port of the packet. If a match is found, the Device will forward the packet to the
mapped localhost. Else, the Dev ice w ill try to find out if there is an available DMZ host.
Port Forwarding
7.2 Static Route
A static route is manually configured by the network administrator, which is stored in a
routing table. By using routing table, the Device can select an optimal transmission
path for each received packet, and forward the packet to the destination site
effectively. The proper usage of static routes can not only improve the network
performance, but also achieve other benefits, such as traffic control, provide a secure
network environment.
The disadvantage of using static routes is that they cannot dynamically adapt to the
current operational state of the network. When there is a change in the network or a
failure occurs, some static routes will be unreachable. In this case, the network
administrator should update the static routes manually.
7.2.1 Static Route List
All static routes you have configured will be displayed in the Static Route List (see the
following figure).

Destination IP: Specify the IP address of the destination network or host.
Subnet Mask: Specify the subnet mask of the destination network or host.
Gateway IP Address: Specify the IP address of the next hop router to which to
forward the packets.
Priority: Specify the priority of the static route. If there are multiple routes to the
same destination with different priorities, the Device will choose the route with the
highest priority to forward the packets. The smaller the number, the higher the
priority.
Interface: Specify the outbound interface through which the packets are
forwarded to the next hop gateway or router. The available options are the name
of eac h physical interface.
Note:
1) When creating a static route, you should specify the next hop IP address by the
Gateway IP Address or Interface.
2) In most cases, please don’t modify the sy stem res erved static route (e.g., Default,
Detect) to avoid surfing the Internet abnormally.
7.3 Policy Routing
This section describes the Advanced > Policy Routing page.
Policy Routing provides a tool for forwarding and routing data packets based on the
user-defined policies. Different from the traditional destination-based routing
mechanism, Policy Routing enables you to use policies based on source and
destination address, protocol, port, schedule, and other criteria to route packets
flexibly.

Note:
Policy Routing takes precedence over the Device’s normal destination-based routing.
That is, if a packet matches all the criteria (source address, destination address,
protocol type, port, etc.) specified in a Policy Routing entry, it will be forwarded
through the outbound interface specified in the Policy Routing entry. If no match is
found in the Policy Routing list, the packet will be forwarded through normal routing
channel (in other words, destination-based routing is performed).
7.4 Anti-NetSniper
This section describes Advanced > Anti-NetSniper page.
Anti-NetSniper is used to crack shared Internet access detection which can be
performed by your ISP. Don't enable this feature unless you encounter the "shared
Internet access detection" issue.
Figure 7-17 Anti-NetSniper
7.5 Plug and Play
Plug and Play is a new feature of UTT series security firewalls. If you enable plug and
play feature on the Device, the LAN users can access the Internet through the Device
without changing any network parameters, no matter what IP address, subnet mask,
default gateway and DNS server they might have. Obviously, this feature can greatly
facilitate the users. As this feature is suitable for hotel network, we also call it hotel
special version.
http://www.uttglobal.com Page 80
UTT Technologies Advanced Menu
Figure 7-18 Plug and Play
Note:
1) The LAN hosts basic TCP/IP parameters (including IP address, subnet mask,
gateway IP address, and DNS server IP address) should be set properly;
otherwise, plug and play feature cannot act on those hosts.
2) Once plug and play is enabled, the Device will automatically enable proxy ARP ,
enable DNS proxy, and disable IP spoofing defense.
3) Once plug and play are enabled, the Device will allow those non-IP/MAC binding
users to access the Device and Internet.
4) The users with the same IP address cannot access the Internet at the same time.
For example, if a LAN user with IP address 1.1.1.1 has connected to the Device
to access the Internet, another user with IP address 1.1.1.1 cannot access the
Internet through the Device.
5) A L AN user’s IP address cannot be the same with the Device’s LAN/WAN
interface IP address, gateway IP address, and primary/secondary DNS server IP
address; otherwise, the user cannot access the Device and Internet.
7.6 Port Mirroring
The port mirroring allows an administrator to mirror and monitor network traffic. It
copies the traffic from the specified ports to another port where the traffic can be
monitored with an external network analyzer. Then the administrator can perform traffic
monitoring, p erformance analysis and fault diagnosis.
