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.

¾

Enable IGMP Snooping:

If you select the option, please choose the IGMP Mode

:

Standard

Mode or Blocking Mode.

¾

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.
