Figure 5- 7. Routing window

The user may configure the following fields for Static routing on the router:

Destination

Enter the host IP address or the remote network that will be used for static routing on

the router.

Netmask

Enter the Subnet Mask to be used for static routing.

Gateway

Enter the gateway device’s IP address. This is an IP address of a device that will

allow the user to contact the remote network or Host IP address. This field cannot be

configured or used if the following field,

Connection

, has been selected.

Connection

Choose a PVC from the corresponding pull-down menu to be used for static routing.

This field cannot be configured or used if the previous field,

Gateway

, has been

selected.

Click

Apply

to set the routing information configured.

DMZ

Firewalls may conflict with certain interactive applications such as video conferencing or playing

Internet video games. For these applications, a firewall bypass can be set up using a DMZ IP address.

The DMZ IP address is a “visible” address and does NOT benefit from the full protection of the

firewall function. Therefore it is advisable that other security precautions be enabled to protect the

other computers and devices on the LAN. It may be wise to use isolate the device with the DMZ IP

address from the rest of the LAN. For example, if you want to use video conferencing and still use a

firewall, you can use the DMZ IP address function. In this case, you must have a PC or server through

which video conferencing will take place. The IP address of this PC or server will then be the DMZ IP

address. You can designate the server’s IP address as the DMZ by typing in the IP address in the

IP

Address

space provided and then enabling its status by clicking the

Enabled

radio button and then

click

Apply

. For the system that uses the DMZ IP address, you may want to manually assign an IP

address to it and adjust your DHCP server addresses so that the DMZ IP address is not included in the

51

DHCP server range. This way you avoid possible IP address problems if you reboot the DMZ system.

To configure the Router’s DMZ IP address, click the

Advanced

tab at the top of the screen and then

the

DMZ

tab to the left.

, the user must choose which services to be filtered by the router using

the corresponding check boxes. The user may choose any combination of these to use for firewalling.

Click

to set these firewall rules to the routers memory.

RIP

The DSL-G604T supports RIP v1 and RIP v2 used to share routing tables with other Layer 3 routing

devices on the LAN, at your ISP’s location or remote networks connected to your network through the

ADSL line. The user may enable or disable RIP v1 (received and sent) or RIP v2. This will enable the

router to send and receive RIP packets. Disabling the RIP function will disable the routing function of

this device.

Figure 5- 10. RIP window

To configure RIP, first use the RIP pull-down menu to enable RIP on the Router. Then select the

protocol to be used by using the pull-down menu. The choices are

RIP v1

,

RIPv1 Compatible

and

RIP v2

. Then the user must choose the direction by selecting

In

,

Out

or

Both

. After making the

configuration choices for RIP, click the

Apply

button to set the configurations in the memory of the

Router.

PPP

The following window is for users employing the PPP protocol as their connection to the ISP. This

window will be specific to PVCs previously configured and will display information concerning the

PVC selected in the WAN configuration window.
