Parameter
Description
User Name
Indicates the user name for connecting to the FTP server. If the
FTP server supports anonymous login, the setting is not required.
Password
Indicates the password for connecting to the FTP server. If the
FTP server supports anonymous login, the setting is not required.
Device
Indicates the drive of the external USB device for saving the file
downloaded through FTP. When the USB storage device is
connected to the USB port, the drop-down list is available.
Local Path
Indicates the path for saving the FTP-downloaded file to the
external USB device. If the path is not entered, the path specified
in Download URL is used by default.
5.8.2 ALG Configuration
1.
In the navigation tree on the left, choose
Network Applications
>
ALG Configuration
.
In the pane on the right, determine whether to enable the FTP or TFTP, as shown in
Figure
5-29
.

ALG Configuration
2.
Click
Apply
to apply the configuration.
When the NAT function is enabled, the application level gateway (ALG) function needs to be
enabled to ensure that some application software and hardware can be normally used.
5.8.3 UPnP Configuration
1.
In the navigation tree on the left, choose
Network Applications
>
UPnP Configuration
.
In the pane on the right, determine whether to enable the UPnP, as shown in
Figure 5-30
.

UPnP Configuration
2.
Click
Apply
to apply the configuration.
Universal Plug and Play (UPnP) is the name of a group of protocols. The UPnP supports zero
configuration networking and automatic discovery of different network devices. If the UPnP is
enabled, the UPnP-enabled device can be dynamically connected to the network to obtain the
IP address, obtain the transfer performance, discover other devices, and learn the performance
of the other devices. The UPnP-enabled device can be automatically disconnected from the
network, without affecting the device or other devices.
When the UPnP is enabled, the LAN-side PC automatically finds the ONT, which is considered
as a peripheral device of the PC and is plug-and-play. After running application software on the
PC, port mapping entries are automatically generated on the ONT through the UPnP protocol,
thus improving the running speed.
5.8.4 ARP Configuration
1.
In the navigation tree on the left, choose
Network Applications
>
ARP Configuration
.
In the pane on the right, click
New
. In the dialog box that is displayed, set the resolution
rule between a MAC address and an IP address, as shown in
Figure 5-31
.

ARP Configuration
2.
Click
Apply
to apply the configuration.
Static ARP means to manually add an ARP entry on an ONT. A static ARP never ages and can
only be deleted manually. If the mapping between the IP address and MAC address of the peer
device is available, configuring a static ARP entry benefits a lot. For example, the dynamic ARP
entry learning is omitted during device communication and the static ARP entry prevents a
device from learning an incorrect ARP entry in the case of malicious attacks.

5.8.5 Portal Configuration
1.
Click the
Network Application
tab and then choose
Portal Configuration
from the
navigation tree. In the right pane, enable/disable the portal function and set the redirection
URL addresses for different types of devices, as shown in
Figure 5-32
.

Click
Apply
to apply the configuration.
If the type of the device that you use is not configured with a URL address or the device type
cannot be identified, the system redirects to the default URL address upon the first access to the
Internet.
5.8.6 DDNS Configuration
1.
Click the
Network Application
tab and then choose
DDNS Configuration
from the
navigation tree. In the right pane, configure DDNS parameters, including
Service
Provider
,
Host Name
,
Service Port
,
Domain Name
,
Username
, and
Password
, as shown
in
Figure 5-33
.

DDNS configuration
2.
Click
Apply
to apply the configuration.
Dynamic domain name service (DDNS) associates a static domain name with the dynamic IP
address of its host.
Assume that server A provides HTTP or FTP service and it is connected to the Internet using
routers. If server A obtains an IP address through DHCP, or server A is connected to the Internet
through PPPoE, PPTP, or L2TP, the IP address is an dynamic IP address. That is, its IP address
may change each time when server A initializes its connection to the Internet.
The mapping between the domain name and IP address provided by the domain name service
(DNS) server is static, and the mapping does not update when the IP address changes. Therefore,
when the IP address of server A changes, users on the Internet cannot access server A with
domain names.
With DDNS, which associates a static domain name with the dynamic IP address of its host,
users on the Internet can access the server only with domain names.
5.8.7 IGMP Configuration
1.
Click the
Network Application
tab and then choose
IGMP Configuration
from the
navigation tree. In the right pane, configure the IGMP parameters, as shown in
Figure
5-34
