Parameter
Description
Bridge Type
It can be set to IP or PPPoE.
Binding options
Used to bind the WAN interface to the
LAN port or to the wireless SSID.
NOTE
Before setting the binding options, set the work
mode of the LAN port or the wireless SSID. The
binding options can be set only after the work
mode or wireless SSID is successfully set. For
details, see
LAN Port Work Mode
and
WLAN Configuration
.
NOTE
l
WAN in route mode: The ONT functions as a gateway. The IP address of the ONT can be obtained
through DHCP, Static, or PPPoE. The IP address of the PC connected to the ONT can be obtained from
the DHCP address pool of the ONT or can be set manually.
l
WAN in bridge mode: The ONT functions as a relay and does not process data. The ONT does not
obtain the IP address allocated by the upper-layer device and it does not allow manual configuration
of a static IP address. The IP address of the device connected to the ONT can be obtained through
DHCP, PPPoE, or static.
l
In the case of the DHCP mode, you need to set the DHCP relay. After configuration is complete,
the user-side IP address is obtained from the upper-layer device. For the detailed procedure, see
DHCP Server Configuration
.
l
In the case of the PPPoE mode, the user-side IP address is obtained through PPPoE authentication
of the upper-layer device.
3.3.3 LAN
This topic describes how to set the working mode of the LAN port, the LAN host, and the DHCP
server through the Web page.
LAN Port Work Mode
1.
Click the
LAN
tab and then choose
LAN Port Work Mode
from the navigation tree. In
the pane on the right, determine whether the LAN port works in layer 3 mode, as shown in
Figure 3-13
.

NOTE
If the check box corresponding to the LAN port is selected, it indicates that the LAN port works in
layer 3 mode, that is, the gateway mode; if the check box corresponding to the LAN port is deselected,
it indicates that the LAN port works in layer 2 mode, that is, the bridge mode.
By default, the check boxes corresponding to all LAN ports are deselected, that is, all LAN ports
work in layer 2 mode.

LAN Host Configuration
1.
Click the
LAN
tab and then choose
LAN Host Configuration
from the navigation tree. In
the pane on the right, set the management IP address and subnet mask of the LAN host, as
shown in
Figure 3-14
.
Figure 3-14
LAN Host Configuration
NOTE
The IP address of the device connected to the LAN port must be in the same subnet as the management
IP address. In this way, you can access an ONT through the Web page and perform query and
management. You can manually set the IP address of the device connected to the LAN port to be on
the same network segment as the management IP address, or start the DHCP server to set the IP
address in the DHCP address pool to be on the same network segment as the management IP address.
For details, see
DHCP Server Configuration
.

DHCP Server Configuration
1.
Click the
LAN
tab and then choose
DHCP Server Configuration
from the navigation tree.
In the pane on the right, you can configure the LAN side DHCP address pool for the ONT
that functions as a gateway. After the configuration, the PC connected to the LAN port can
automatically obtain an IP address from the address pool, as shown in
Figure 3-15
.

Parameter
Description
Enable DHCP L2 Relay
Indicates whether to enable the DHCP L2
Relay.
The DHCP relay is a process in which cross-
subnet forwarding of DHCP broadcast
packets is implemented between the DHCP
client and the DHCP server. In this manner,
the DHCP clients in different physical
subnets can obtain IP addresses which are
dynamically allocated from the same DHCP
server.
l
If
Mode
of the WAN port is
Route
, the IP
address of the ONT is obtained from
upper-layer DHCP servers in different
subnets and the user-side IP addresses are
obtained from the DHCP address pool of
the ONT.
l
If
Mode
of the WAN port is
Bridge
, the
ONT functions as a bridge. Thus, the ONT
does not have an IP address. The user-side
IP addresses are obtained from upper-
layer DHCP servers in different subnets.
Start IP Address
Indicates the start IP address in the IP address
pool on the primary DHCP server. It must be
in the same subnet as that of the IP address set
in "
LAN Host Configuration
". Otherwise,
the DHCP server fails to work normally.
End IP Address
Indicates the end IP address in the IP address
pool on the active DHCP server. It must be in
the same subnet as that of the IP address set
in "
LAN Host Configuration
". Otherwise,
the DHCP server fails to work.
Leased Time
Indicates the lease time of the IP address pool
on the active DHCP server. Options: minute,
hour, day, and week.
Enable secondary DHCP server
Indicates whether to enable the secondary
DHCP server. If the check box is selected,
you can set the secondary DHCP server.
IP Address
Indicates the IP address of the secondary
DHCP server.
Subnet Mask
Indicates the subnet mask of the secondary
DHCP server.
Start IP Address
Indicates the start IP address in the IP address
pool on the secondary DHCP server.

Description
End IP Address
Indicates the end IP address in the IP address
pool on the secondary DHCP server.
Leased Time
Indicates the lease time of the IP address pool
on the secondary DHCP server. Options:
minute, hour, day, and week.
Option60
Indicates the option 60 field of the secondary
DHCP server. A user-side DHCP client can
obtain an IP address from the IP address pool
on the secondary DHCP server only when the
option 60 field carried by the user-side DHCP
client is the same as this setting.
