12

DCM-604 Cable Modem EMTA Gateway User’s Manual

5.3 Basic

The Basic page contains the basic features of DCM-604 including Setup,
DHCP and Backup

5.3.1 Setup

This setup page allows configuring the basic features of the broadband gateway
related to your ISP's connection.

5.3.2 DHCP

The DHCP page allows you to activate/deactivate the DHCP server function
of the DCM-604, and, if the DHCP server is activated, to see DHCP leases it
has provided.

13

DCM-604 Cable Modem EMTA Gateway User’s Manual

With this function activated, your cable service provider’s DHCP server
provides one IP address for the DCM-604, and the DCM-604’s DHCP server
provides IP addresses, starting at the address you set in Starting Local
Address field, to your PCs. A DHCP server leases an IP address with an
expiration time.

To set the maximum number of PCs to which the DCM-604 will issue IP
addresses, enter it in the Number of CPEs box and then click Apply. (CPE is
another term sometimes used for PC.)

The table on the bottom of this page shows the information of DHCP clients
including the IP and MAC addresses of each PC. Since MAC addresses are
unique and permanently fixed into hardware, you can identify any PC listed by
its MAC address. The DCM-604 provides leases for 3600 seconds (default),
and has an automatic renewal mechanism that will keep extending a lease as
long as the associated PC remains active.

You can cancel an IP address lease by selecting it in the DHCP Client Lease
Info list and then clicking the Force Available button. If you do this, you may
have to perform a DHCP Renew on that PC, so it can obtain a new lease.

5.3.3 Backup

This page allows you to save your current settings locally on your PC, or restore
previously saved settings.

5.4 Advanced

The Advanced page allows you to enable/disable some advanced features of
the DCM-604.

14

DCM-604 Cable Modem EMTA Gateway User’s Manual

5.4.1 Options

The Options page allows you to enable/disable some advanced features
supported by DCM-604.

Check the option you want to use and click Apply button to enable the
function(s).

 WAN Blocking: To prevent others on the WAN side from being able to

ping your DCM-604. With WAN Blocking on, your DCM-604 will not
respond to pings it receives, effectively “hiding” your gateway.

 IPSec Pass-through: To enable IPSec type packets to pass through

between WAN and LAN.

 PPTP Pass-through: To enable PPTP type packets to pass through

between WAN and LAN.

 Remote Config Management: To make the Web Management pages of

your DCM-604 accessible from the WAN side. Page access is limited to
only those who know the DCM-604 access password you set in the
Status--Security page.
When accessing the DCM-604 from a remote location, you must use
HTTP port 8080 and your IP address. This is the "WAN IP address" that
appears at the Basic--Setup page. For example, if this IP address were

211.20.15.28, you would navigate to http:// 211.20.15.28:8080 to reach
the DCM-604’s Web Management page from a remote location.

 Multicast Enable: To enable multicast traffic to pass through between

WAN and LAN. You may need to enable this to see some types of
broadcast streaming and content on the Internet, such as webcasting of a
popular live event.

 UPnP Enable: UPnP (Universal Plug and Play) offers pervasive peer-to-

peer network connectivity of PCs of all form factors, intelligent appliances,
and wireless devices. UPnP architecture leverages TCP/IP and the Web
to enable seamless proximity networking in addition to control and data
transfer among networked devices in the home, office, and everywhere in
between.

15

DCM-604 Cable Modem EMTA Gateway User’s Manual

5.4.2 IP Filtering

The IP Filtering page enables you to enter the IP address ranges of PCs on
your LAN that you don’t permit to have outbound access ability to the WAN.
These PCs can still communicate with each other on your LAN, but packets
they originate to WAN addresses are blocked by the DCM-604.

To enable IP Filtering feature of DCM-604, check the Enable box and click

Apply button.

5.4.3 Port Filtering

The Port Filtering page allows you to enter ranges of destination ports
(applications) that you don’t want your LAN PCs to send packets to. Any
packets your LAN PCs send to these destination ports will be blocked. For
example, you could block access to worldwide web browsing (HTTP port 80)
but still allow email service (SMTP port 25 and POP3 port 110).

To enable port filtering, enter the Start port and End port for each range.
Then select its protocol form the drop-down list and check the Enable box,
and click Apply button. To block only one port, set both Start and End ports
the same.

16

DCM-604 Cable Modem EMTA Gateway User’s Manual

5.4.4 Forwarding

For communications between LAN and WAN, the DCM-604 normally only
allows you to originate an IP connection with a PC on the WAN; it will ignore
attempts of the WAN PC to originate a connection onto your PC. This protects
you from malicious attacks from outsiders. However, sometimes you may wish
for anyone outside to be able to originate a connection to a particular PC on
your LAN if the destination port (application) matches one you specify.

The Forwarding page allows you to specify up to 10 rules.

Using the Port Forwarding page, you can provide local services (web servers,
FTP servers, mail servers, etc) for people on the Internet or play Internet
games. A table of commonly used port numbers is also provided.

5.4.5 Port Triggers

The Port Triggers page allows you to configure dynamic triggers to specific
devices on the LAN. This allows for special applications that require specific
port numbers with bi-directional traffic to function properly. Applications such
as video conferencing, voice, gaming, and some messaging program features
may require these special settings.

17

DCM-604 Cable Modem EMTA Gateway User’s Manual

Port Triggering is an elegant mechanism that does the forwarding for you,
each time you play the game.

You can specify up to 10 port ranges on which to trigger.

5.4.6 DMZ Host

The DMZ page allows you to configure a specific network device to be
exposed or visible directly to the WAN (public Internet). Setting a host on your
local network as demilitarized zone (DMZ) forwards any network traffic that is
not redirected to another host via the port forwarding feature to the IP address
of the host (PC). This designates one PC on your LAN that should be left
accessible to all PCs from the WAN side for all ports. For example, if you
locate a HTTP server on this machine, anyone will be able to access that
HTTP server by using your DCM-604’s IP address as the destination. This
may be used when problem applications do not work with port triggers. The
setting of “0” indicates NO DMZ PC.

18

DCM-604 Cable Modem EMTA Gateway User’s Manual

5.5 Firewall

The DCM-604 provides built-in firewall functions, enabling you to protect the
system against denial of service (DoS) attacks and other unwelcome or
malicious accesses to your LAN.

5.5.1 Web Filter

This page allows certain Web-oriented cookies, java scripts, and pop-up windows to
be blocked by the firewall. A list of "trusted computers" can also be defined that are
not subject to any filters configured. Specific Firewall features can also be enabled. It
is highly recommended that the Firewall is left enabled at all times for protection
against Denial of Service attacks. Go to the Parental Control page to block internet
access to specific sites.

5.5.2 Local Log

The Local Log page allows you to configure the firewall event log reported via
email alert, and these attack records are also visible in the table on the bottom
of this page.

19

DCM-604 Cable Modem EMTA Gateway User’s Manual
