6.1 Route Setup

6.1.1 Static Route Setup

You may need to define routes if your home setup includes two or more networks or

subnets, if you connect to two or more ISP services, or if you connect to a remote

corporate LAN.

Fields in this page:

Description

Enable

Check to enable the selected route or route to be added.

Destination

The network IP address of the subnet. The destination can be specified as the IP

address of a subnet or a specific host in the subnet. It can also be specified as all

zeros to indicate that this route should be used for all destinations for which no

other route is defined (this is the route that creates the default gateway).

Subnet Mask

The network mask of the destination subnet. The default gateway uses a mask of

0.0.0.0.

Next Hop

The IP address of the next hop through which traffic will flow towards the

destination subnet.

Metric

Defines the number of hops between network nodes that data packets travel. The

default value is 0, which means that the subnet is directly one hop away on the

local LAN network.

Interface

The WAN interface to which a static routing subnet is to be applied.

Function buttons in this page:

Add Route

6.1.2 IPv6 Routing Configuration

IPv6 configuration is mostly the same as IPv4 configuration (please refer to 6.1 Static Route

Setup). IPv4 uses only 32 bits for IP address space, IPv6 allows 128 bits for IP address space.

6.1.3 RIP Configuration

RIP is an dynamic routing Internet protocol. Here you can set up to share routing table

information with other routing devices on your LAN, at your ISP’s location, or on remote

networks connected to your network via the ADSL line.

Most small home or office networks do not need to use RIP; they have only one router, such as

the ADSL Router, and one path to an ISP. In these cases, there is no need to share routes,

because all Internet data from the network is sent to the same ISP gateway.

You may want to configure RIP if any of the following circumstances apply to your network:

o

Your home network setup includes an additional router or RIP-enabled router (other than

the ADSL Router). The ADSL Router and the router will need to communicate via RIP to

share their routing tables.

o

Your network connects via the ADSL line to a remote network, such as a corporate

network. In order for your LAN to learn the routes used within your corporate network,

they should both be configured with RIP.

o

Your ISP requests that you run RIP for communication with devices on their network.

6.2 NAT Configuration

In computer networking, network address translation (NAT) is the process of modifying IP

address information in IP packet headers while in transit across a traffic routing device.

6.2.1 DMZ Setup

A DMZ (Demilitarized Zone) allows a single computer on your LAN to expose ALL of its

ports to the Internet. Enter the IP address of computer as a DMZ (Demilitarized Zone)

host with unrestricted Internet access. When doing this, the DMZ host is no longer

behind the firewall.

Check this item to enable the DMZ feature.

DMZ Host IP Address

IP address of the local host. This feature sets a local host to be exposed

to the Internet.

6.2.2 Virtual Server

Firewall keeps unwanted traffic from the Internet away from your LAN computers.

Add a Virtual Server entry will create a tunnel through your firewall so that the

computers on the Internet can communicate to one of the computers on your

LAN on a single port.
