VLAN:
Enable or disable this function. Virtual LAN (VLAN) is a group of devices on one or
more LANs that are configured so that they can communicate as if they were attached to the
same LAN, when in fact they are located on a number of different LAN segments. Because
VLANs are based on logical instead of physical connections, it is very flexible for user/host
management, bandwidth allocation and resource optimization. If you want to active this
function, this function must be enabled.
)
Note:
It is not allowed to disable the VLAN with Ethernet Connection enabled.
To support this feature, you must create mapping groups with appropriate LAN and WAN
interfaces using the
Add
button. The
Remove
button will remove the grouping and add the
ungrouped interfaces to the Default group. Only the default group has IP interface.
Click the
Add
button. You can add a new interface group in the next screen. For example, you
want LAN1 and LAN3 to be a group called Group 1 over br_0_35_0 WAN interface, you can refer
to the following figure.

IP Address:
You can configure the Modem Router’s IP Address and Subnet Mask for LAN
Interface.
IP Address:
Enter the Modem Router’s local IP Address, then you can access to the
Web-based Utility via the IP Address, the default value is 192.168.1.1.
Subnet Mask:
Enter the Modem Router’s Subnet Mask, the default value is
255.255.255.0.

Enable IGMP Snooping:
If you select the option, please choose the IGMP Mode
:
Standard
Mode or Blocking Mode.

Enable Second IP:
You can configure the Modem Router’s second IP Address and Subnet
Mask for LAN Interface through which you can also access to the Web-based Utility as the
default IP Address and Subnet Mask.
¾
DHCP Server:
These settings allow you to configure the Modem Router‘s Dynamic Host
Configuration Protocol (DHCP) server function. The DHCP server is enabled by default for the
Modem Router’s Ethernet LAN interface. DHCP service will supply IP settings to computers
which are configured to automatically obtain IP settings that are connected to the Modem
Router though the Ethernet port. When the Modem Router is set for DHCP, it becomes the
default gateway for DHCP client connected to it. Keep in mind that if you change the IP
address of the Modem Router, you must change the range of IP addresses in the pool used
for DHCP on the LAN.
Start IP Address:
Enter a value for the DHCP server to start with when issuing IP
addresses. Because the default IP address for the Modem Router is 192.168.1.1, the
default Start IP Address is
192.168.1.100
, and the Start IP Address must be 192.168.1.100
or greater, but smaller than 192.168.1.254.
End IP Address:
Enter a value for the DHCP server to end with when issuing IP
addresses. The End IP Address must be smaller than 192.168.1.254. The default End IP
Address is
192.168.1.254
.

Leased Time:
The Leased Time is the amount of time in which a network user will be
allowed connection to the Modem Router with their current dynamic IP address. Enter the
amount of time, in hours, then the user will be “leased” this dynamic IP address. After the
dynamic IP address has expired, the user will be automatically assigned a new dynamic IP
address. The default is
1440
minutes.
