4.4.2.1 Defining the Private IP Address for the DSL Router
In this page, you can change the IP address of the device. The preset IP address is
192.168.1.1. This is the private IP address of the DSL Router, under which the device
can be reached in the local network. It can be freely assigned from the block of
available addresses. The IP address under which the Router can be reached from
outside is assigned by the ISP.
• If you want to assign a different IP address to the DSL Router, enter it in the field
next to IP address.
• Adjust the subnet mask if necessary.
It is recommended to use an address from a block that is reserved for private use.
The address block is 192.168.1.1~192.168.255.254.
Note: New settings can only be made after the DSL Router is rebooted. If necessary,
reconfigure the IP address on your PC (including the one that is statically assigned)
so that it matches the new configuration.
4.4.2.2 Enabling IGMP Snooping
Internet Group Management Protocol
IGMP is an Internet protocol that enables an Internet computer to inform neighboring
routers that it is a member of a multicast group. With multicasting, a computer can
send content on the Internet to several other computers that have registered an
interest in the content of the first computer. Multicasting can, for example, be used for
multimedia programs for media streaming to recipients that have set up multicast
group membership.
Note: If IGMP snooping function is enabled, the DSL Router capability improves.
4.4.2.3 Configuring the DHCP Server
The DSL Router has a DHCP server for which the factory setting is active.
Consequently, the IP addresses of the PCs are automatically assigned by the DSL
Router.
47
Page 48
DG-BG1100U User Manual
Note:
• If the DHCP server for the DSL Router is activated, you can configure the network
setting on the PC so that the option ‘Obtain an IP address automatically’ is set up.
• If you deactivate the DHCP server, you need to assign a static IP address for the
PCs that use the network settings.
• If the DHCP server is active, you can define a lease time. The lease time
determines the period for which the PCs retain the IP addresses assigned to them
without changing them.
• Define the range of IP addresses that the Router should use to automatically
assign IP addresses to the PCs. Define the first issued IP address and the last
issued IP address.
• Enable DHCP Server Relay: This function allows you to relay DHCP and BOOTP
requests from a subnet with no DHCP server on it to one or more DHCP servers
on other subnets.

4.4.4 Security
Security is an important function of DSL. It protects resources of a private network from
users from other networks, and prevents unauthorized Internet users from accessing
private networks connected to the Internet. All messages entering or leaving the
intranet (that is, the local network to which you are connected) must pass through the
security checks, which checks each message and blocks those that do not meet the
specific security criteria.
There are two basic types of security techniques:
• IP packet filtering: The system checks each packet entering or leaving the
network and accepts or rejects it based on user-defined rules. Packet filtering is
fairly effective and transparent to users, but is difficult to configure.
• Parental Control: The system checks each frame entering or leaving the network
from layer 2. It accepts and rejects frames according to user-defined rules.
Choose Security > IP Filtering and the following page appears. By default, the firewall
is enabled. The firewall is used to block document transmissions between the Internet
and your PC. It serves as a safety guard and permits only authorized documents to be
sent to the LAN.
Note: If the router is configured to bridge mode only, IP filtering is disabled and the IP
filtering interface does not appear.
If no PVC of Bridge mode is configured, MAC filtering is disabled and the MAC
Filtering interface does not appear.

4.4.5 Quality of Service
Many communication and multimedia applications require large, high speed bandwidths
to transfer data between the local network and the Internet. However, for many
applications there is often only one Internet connection available with limited capacity.
QoS divides this capacity between the different applications and provides undelayed and
continuous data transfer where data packets with higher priority are given preference.
Click Quality of Service and the following page appears. Under Quality of Service,
there are two network share modes: Queue Config and QoS Classification.
4.4.5.1 Enabling QoS
In this page, you can configure QoS queue management. By default, the system enables
QoS and sets a default DSCP mark to automatically mark incoming traffic without
reference to particular classifier.
Choose Advance Setup > Quality of Service and the following page appears:
Select Enable QoS to enable QoS and set the default DSCP mark.
Click Save/Apply to active QoS.
62
Page 63
DG-BG1100U User Manual
4.4.5.2 QoS - Queue Configuration
The queuing in packet QoS becomes effective only when packet is forwarded to QoSenabled PVC. Packet forwarding is determined by IP routing or bridging, not under
control of the packet QoS.
Click Queue Config and the following page appears. In this page, you can configure
QoS Queue. A maximum of 24 entries can be configured.
QoS Queue Configuration can allocate three queues. Each of the queues can be
configured for a precedence value. The queue entry configured is used by the classifier
to place ingress packets appropriately.
Note: Lower integer values for precedence indicate higher priority for this queue
relative to others.
Click Add and the following page appears.
Queue Configuration Status: Set to enable or disable a QoS queue.
Queue: Select a specific network interface. The router automatically allocates selected
network interface to the queue.
Queue Precedence: Select an integer value for queue precedence. After you select an
integer value, the queue entry appropriately places to ingress packets. Lower integer
values for precedence imply higher priority for this queue relative to others.
63

DG-BG1100U User Manual
4.4.5.3 QoS - QoS Classification
Some applications require specific bandwidth to ensure their data be forwarded in time.
QoS classification can creates traffic class rule to classify the upstream traffic. Assign
queue which defines the precedence and the interface and optionally overwrite the IP
header DSCP byte. After QoS classification, QoS divides capacity between different
applications and provides undelayed and continuous data transfer where data packet
with higher priority is given preference.
Click QoS Classification and the following page appears. In this page, you can
configure network traffic classes.
Click Add, and the following page appears.

• Traffic Class Name: Enter a name of the class.
• Rule Order: Select order for queue.
• Rule Status: Enable or disable this traffic class rule.
• Assign Classification Queue: Select a classification queue.
• Assign Differentiated Service Code Point (DSCP) Mark: Select a mark service
that modifies the original packet IP header if all rules defined within the
classification class are matched. (CS - Mark IP Precedence, AF - Assured
Forwarding, EF - Expedited Forwarding)
• Mark 802.1p if 802.1q is enabled: Select an 802.1p priority number that serves as
the 802.1p value.
There are two sets of classification rules. Set-1 is based on different fields within
TCP/UDP/IP layer plus physical LAN port; Set-2 is based on MAC layer IEEE 802.1p
priority field.
802.1p priority: The 802.1p header includes a 3-bit prioritization field, which allows
packets to be grouped into eight levels of priority (0-7), where level 7 is the highest
one.

4.4.6.2 Static Routes
Networking devices forward packets using route information that is either manually
configured or dynamically learned using a routing protocol. Static routes are manually
configured and define an explicit path between two networking devices. Unlike a
dynamic routing protocol, static routes are not automatically updated and must be
manually reconfigured if the network topology changes. The benefits of using static
routes include security and resource efficiency. Static routes use less bandwidth than
dynamic routing protocols and no CPU cycles are used to calculate and communicate
routes. The main disadvantage to using static routes is the lack of automatic
reconfiguration if the network topology changes.
Static routes can be redistributed into dynamic routing protocols but routes generated
by dynamic routing protocols cannot be redistributed into the static routing table. No
algorithm exists to prevent the configuration of routing loops that use static routes.
Static routes are useful for smaller networks with only one path to an outside network
and to provide security for a larger network for certain types of traffic or links to other
networks that need more control. In general, most networks use dynamic routing
protocols to communicate between networking devices but may have one or two static
routes configured for special cases.
Adding Static Route
Step 1 Enter destination network address.
Step 2 Enter subnet Mask.
Step 3 Enable Use Gateway IP Address and enter IP address.
Step 4 Select use interface.
Step 5 Click Save/Apply to apply the settings.
Remove static route
Select Remove box in the table, and click Remove to apply the settings.

4.4.7.2 Dynamic Domain Name Service (DDNS)
Overview
Dynamic DNS allows binding of domain names to hosts with dynamically assigned IP
addresses by a Dynamic Host Control Protocol (DHCP) server and updates the name
server with the new information about the host or the network. This is particularly
useful for broadband users to use Internet services, such as FTP, Hyper Text Transfer
Protocol (HTTP), and Simple Mail Transfer Protocol (SMTP), on their local hosts
connected to the broadband network. Dynamic DNS allows access to such hosts
connected to the broadband networks using a domain name to exchange files, send
and receive email with highly personalized email addresses, and host a website.
To provide such support for the feature described above, a client is installed in the host
that directs Internet traffic to the domain. The client updates the IP address of the host,
whenever the host renegotiates the IP address for any reason. The Router reference
software allows users to configure the following dynamic DNS servers for DDNS
service:
• DynDNS.org: A free DNS service for hosts with dynamic IP addresses.
• TZO: A service provider providing paid dynamic and static DNS services.
To use one of the providers mentioned above requires the users to register with the
dynamic DNS service provider the information about the host and the installed client
software on the host which can update the service provider with the IP address and the
domain name information.
