How Do I Configure the Gateway Cable Modems?

To configure your gateway cable modem, you must access the WebWizard configuration pages. This section provides detailed instructions and procedures for configuring your gateway cable modem to operate correctly and presents an example of each WebWizard page. Use the WebWizard pages to customize your gateway cable modem to your needs rather than using the default settings.

The WebWizard pages and the examples shown in this section are for illustration purposes only. Your pages will differ from the pages shown here.

If you are not familiar with the network configuration procedures detailed in this section, contact your cable service provider before you attempt to change any of the gateway cable modem default settings.

Configuring the Gateway Cable Modem

You must access the WebWizard in order to configure the gateway cable modem. To gain access to the WebWizard, use the Web browser on the PC attached to the cable modem. Type the following IP address and then select Go:http://192.168.0.1

The Web browser accesses the WebWizard and displays the default About Your

Modem page. This page displays information about the gateway cable modem.

Field Name

Description

Port Forwarding

Use this page to configure port forwarding for local IP

 

addresses. Port forwarding allows you to run a server

 

on the local area network (LAN) by specifying the

 

mapping of TCP/UPD ports to local PCs or to the IP

 

address of other devices. This is a static setting that

 

holds the ports open at all times

Port Triggers

Use this page to configure TCP/UPD port triggers.

 

Port triggering is similar to port forwarding, but is a

 

dynamic function. In other words, the ports are not

 

held open, and the ports close if no outgoing data is

 

detected on the selected ports for a period of 10

 

minutes

DMZ Host

Use this page to configure an IP address that is visible

(Demilitarized Zone)

to the wide area network (WAN). DMZ hosting is

 

commonly referred to as “exposed host,” and allows

 

you to specify the “default” recipient of WAN traffic

 

that Network Address Translation (NAT) is unable to

 

translate to a known local PC.

 

A DMZ is used by a company that wants to host its

 

own Internet services without sacrificing unauthorized

 

access to its private network. DMZ allows one IP

 

address to be unprotected while others remain

 

protected. The DMZ is located between the Internet

 

and an internal network’s line of defense that is a

 

combination of firewalls and bastion hosts.

 

Typically, the DMZ contains devices accessible to

 

Internet traffic, such as Web (HTTP) servers, FTP

 

servers, SMTP (e-mail)servers, and domain name

 

system (DNS) servers

Firewall

The following table provides a description of the pages available from within the

Firewall section of the Setup page.

Field Name

Web Filters

Time of Day Filters

Event Logging

Description

Use this page to configure Web page filtering, parental control, and firewall protection. This page allows you to block/allow Internet access based on keywords and/or domain names

Use this page to block all traffic to and from specific computers based on the day of week and the time of day

Use this page to access the firewall event log and to enter your e-mailaddress in order to receive e- mail alerts related to firewall attacks by hackers
