Figure 20. Example of DMZ Host Page

To configure DMZ settings:

1

Enter the last byte of the LAN IP address of the PC or other device on your network that you

want to configure as a DMZ host.

2

Click

Apply

.

Note:

If a specific PC is set as a DMZ Host, remember to set this back to “0” when finished with

the needed application, since this PC will be effectively exposed to the public Internet.

Note:

You may need to assign your DMZ host a static IP address on your LAN to insure that it

will always be at that address.

RIP Setup

The RIP Setup page allows you to configure RIP (Router Information Protocol) parameters. RIP

automatically identifies and uses the best known and quickest route to any given destination address

to help reduce network congestion and delays.

RIP is a protocol that requires negotiation from both sides of the network (e.g. both the cable

modem/router and your service provider’s CMTS (Cable Modem Termination System)). Your

service provider will normally set this up based on their knowledge of their CMTS settings.

To access the

RIP Setup

page:

1

Click

Advanced

in the menu bar.

2

Then click the

RIP Setup

submenu.

Figure 21 shows an example of the menu and Table 15 describes the items you can select.

Figure 21. Example of RIP Setup Page

Note:

RIP messages will only be sent when the cable modem/router is configured for Static IP Addressing

(see the

Basic – Setup

page).

It is unlikely that your cable Internet service supports this mode. If they do, and you want to enable

RIP, you will need to ask for the CMTS’s key name and number. You may need additional

information.

To enable the cable modem/router to perform RIP, do the following (this example uses BRCMV2 as

the RIP Authentication Key and 1 as the Key ID):

•

To turn on RIP MD5 Authentication, and check the

Enable

box.

•

To specify a RIP MD5 Authentication Key String, type

BRCMV2

for this example.

key name = a string value to match CMTS key name value

•

To specify a RIP MD5 Auth Key ID, type

1

.

key number = a number to match the CMTS key number value

•

To change the RIP announcement interval, enter a number in seconds.

reporting interval by default = 30 seconds

•

To specify a RIP unicast destination IP address, enter the IP address and subnet mask.
