Advanced Setup Tab - DMZ Host

Broadband Router

Advanced Setup Tab - DMZ Host

The DMZ (Demilitarized Zone) Host feature allows one local user to be exposed to the Internet, not protected by

the Router’s firewall, to use a special-purpose service such as Internet gaming or video conferencing.

Check the

Enable DMZ Host

box to use this feature. Then, enter the

DMZ Private IP Address

, which is the IP

Address of the PC using this feature. The Default value zero (0) will deactivate the DMZ Host.

Click the

Save Settings

button to save the DMZ Host setting or click the

Cancel Changes

button to undo the

changes.

Advanced Setup Tab - Forwarding

Port forwarding can be used to set up public services on your network. When users from the Internet make

certain requests of your network, the Router can forward those requests to computers equipped to handle them.

If, for example, you set port number 80 (HTTP) to be forwarded to IP Address 192.168.1.2, then all HTTP requests

from outside users will be forwarded to 192.168.1.2.

You may use this function to establish a Web server or FTP server via an IP Gateway. Be sure that you enter a valid

IP Address. (You may need to establish a static IP address in order to properly run an Internet server.) For added

security, Internet users will be able to communicate with the server, but they will not actually be connected. The

packets will simply be forwarded through the Router.

Chapter 5: Setting Up and Configuring the Broadband Router

Advanced Setup Tab - DDNS

Broadband Router

Advanced Setup Tab - DDNS

DDNS (Dynamic DNS) service allows you to assign a fixed domain name to a dynamic Internet IP address. This

allows you to host your own Web, FTP or other type of TCP/IP server in your LAN over either of the Internet ports.

Before configuring DDNS, you need to visit

www.dyndns.org

and register a domain name. (The DDNS service is

provided by DynDNS.org).

DDNS Service

: The DDNS feature is disabled by default. To enable this feature, select

DynDNS.org

from the

pull-down menu, and enter the

User name

,

Password

, and

Host Name

of the account you set up with

DynDNS.org.

Internet IP Address

: The current Internet IP Address of the Internet port being utilized is displayed here.

Because it is dynamic, this will occasionally change.

Status

: The status of the DDNS function and Internet connection is displayed.

Click the

Save Settings

button to save the DDNS settings or click the

Cancel Changes

button to undo your

changes.

Advanced Setup Tab - Advanced Routing

Dynamic Routing

The Router's dynamic routing feature can be used to automatically adjust to physical changes in the network's

layout. The Router uses the dynamic RIP protocol. It determines the route that the network packets take based on

the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts

routing information to other routers on the network.

Working Mode

: Select

NAT

mode if this Router is hosting your network’s connection to the Internet. Select

Router

mode if this Router exists on a network with other routers, including a separate network gateway that

handles the Internet connection. In Router Mode, any computer connected to the Router will not be able to

connect to the Internet unless you have another router function as the gateway.

RIP

(Routing Information Protocol): The Router, using the RIP protocol, calculates the most efficient route for the

network’s data packets to travel between the source and the destination, based upon the shortest paths.

Receive RIP versions

: Choose a protocol for receiving data from the network. (None, RIPv1, RIPv2, Both RIPv1

and v2).

Advanced Setup Tab - Advanced Routing

Broadband Router

Transmit RIP versions

: Choose a protocol for transmitting data on the network. (None, RIPv1, RIPv2-Broadcast,

RIPv2-Multicast)

Static Routing

You will need to configure Static Routing if there are multiple routers installed on your network. The static routing

function determines the path that data follows over your network before and after it passes through this Router.

You can use static routing to allow different IP domain users to access the Internet.

In many cases, it is better to use dynamic routing (see above), as that allows the Router to automatically adjust to

physical changes in the network's layout. In order to use static routing, the Router's DHCP settings must be

disabled.

To set up static routing, add routing entries in the Router's table that tell the device where to send all incoming

packets. All of your network routers should direct the default route entry to this Router.

Enter the following data to create a static route entry:

1.

Destination IP

: Enter the network address of the remote LAN segment. For a standard Class C IP domain, the

network address is the first three fields of the Destination LAN IP, while the last field should be zero.

2.

Subnet Mask

: Enter the Subnet Mask used on the destination LAN IP domain. For Class C IP domains, the

Subnet Mask is 255.255.255.0.

3.

Default Gateway

: If this Router is used to connect your network to the Internet, then your gateway IP is the

Router's IP Address. If you have another router handling your network's Internet connection, enter the IP

Address of that router instead.

4.

Hop Count

(max. 15): This value gives the number of nodes that a data packet passes through before

reaching its destination. A node is any device on the network, such as switches, PCs, etc.

5.

Interface

(LAN, Internet1, Internet2): Select whether your network is on the LAN or one of the Internet ports.

If you’re connecting to a sub-network, select

LAN

. If you’re connecting to another network through one of the

Internet ports, select

Internet1

or

Internet2

.

Click

Add to list

to add a static route entry or click

Delete Selected IP

to delete the static route entry.

Click the

Save Settings

button to save the Routing settings, click the

Cancel Changes

button to undo your

changes or click the

Show Routing Table

button to view the current routing table.

NOTE:

Static Routing is an

advanced feature
