DESCRIPTION

IP Address

Enter the LAN IP address you want to assign to your Router. The factory default is

192.168.1.1.

IP Subnet Mask

Type the subnet mask of your network. The factory default is 255.255.255.0. Your

Router automatically computes the subnet mask based on the IP address you enter,

so do not change this field unless you are instructed to do so.

RIP Version

Specify the RIP (Routing Information Protocol) version, which allows a router to

exchange routing information with other routers.

Direction

Specify how much routing information the Router sends and receives on the subnet.

Multicast

IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to

establish membership in a multicast group.

IGMP Snooping

Select

Enabled

to activate IGMP Snooping. This allows the Router to passively learn

memberships in multicast groups. Otherwise, select

Disabled

to deactivate it.

IGMP Quickleave

Select

Enabled

to immediately removes a port when the Router detects an IGMP

version 2 leave message on that port.

DHCP

Select

Enable

to have the Router assign IP addresses, an IP default gateway and DNS

servers to LAN computers and other devices that are DHCP clients.

Select

DHCP Relay

to to have the Router forward DHCP requests to the DHCP

server.

If you select

Disable

, you need to manually configure the IP addresses of the

computers and other devices on your LAN.

You need to configure the following fields if you select

Enable

or

DHCP Relay

.

DHCP Relay Server

Address

If you set

DHCP

to

DHCP Relay

, enter the IP address pf the DHCP relay server.

IP Pool Starting

Address

Specify the first of the contiguous addresses in the IP address pool.

Pool Size

Specify the size, or count of the IP address pool.

State

Select

Enable

to enable the DHCP conditional serving pool for IPTV set-top boxes.

DHCP server will offer IP address from the conditional pool if the DHCP request sent

from a set-top box contains the specific Vendor ID.

Gateway

Enter the IPTV server’s IP address.

Subnet Mask

Enter the IPTV server’s subnet mask.

Pool Start/End

Specify the first and last of the contiguous addresses in the IPTV server’s IP address

pool.

DNS Server 1/2

Enter the IPTV server’s first/second DNS server IP address.

VendorID

Specify the IPTV’s vendor ID.

The Static DHCP Screen

Use the

Static DHCP

screen to change your Router’s static DHCP settings. This table allows you to

assign IP addresses on the LAN to specific individual computers based on their MAC Addresses. Find

out the MAC addresses of your network devices if you intend to add them to the

Static DHCP

screen.

VendorID Mode

Specify the IPTV’s vendor ID mode type.

VendorID Exclude

Specify if you want to enable vendor ID exlude.

Option240 State

Select

Enabled

to have the Router multimedia acquire values of option 240 when

acquiring parameters of WAN2 interface.

Option240 Value

Enter the option 240 value.

Lease Time

Specify for how long it takes to assign an IP address to a LAN device before making it

available for reassignment to other systems.

DNS Server 1/2

Select

Obtained From ISP

if your ISP dynamically assigns DNS server information

(and the Router's WAN IP address).

Select

User-Defined

if you have the IP address of a DNS server. Enter the DNS

server's IP address in the field to the right.

Select

DNS Proxy

to have the DHCP clients use the Router’s own LAN IP address.

The Router works as a DNS relay.

Select

None

to not configure extra DNS servers.

MAC Address

Enter the MAC address of a computer on your LAN.

IP Address

Enter the IP address that you want to assign to the computer on your LAN.

8.3

The IP Alias Screen

IP alias allows you to partition a physical network into different logical networks over the same

Ethernet interface. The Router supports multiple logical LAN interfaces via its physical Ethernet

interface with the Router itself as the gateway for the LAN network.

When you use IP alias, you can also configure firewall rules to control access to the LAN's logical

network (subnet).

MAC Address

This field displays the MAC address of the client on the LAN.

IP Address

This field displays the IP address of the client on the LAN.

IP Address

Enter the second LAN IP address of your Router.

Subnet Mask

Your Router will automatically calculate the subnet mask based on the IP address

that you assign. Unless you are implementing subnetting, use the subnet mask

computed by the Router.

8.4

The UPnP Screen

Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for

simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a

network, obtain an IP address, convey its capabilities and learn about other devices on the network.

In turn, a device can leave a network smoothly and automatically when it is no longer in use.

Use the

UPnP

screen to enable the UPnP feature on your Router. Click
