WAN Blocking
Blocks connection requests initialized from Internet users
when enabled. WAN Blocking must be disabled to be able to
PING the WAN gateway IP.
Ipsec PassThrough
Forces the router to redirect the IPSec request to the local
host when enabled. NAT fails this attempt if Internet users
initialize an IPSec VPN request to a host located behind the
router.
PPTP PassThrough
Forces the router to redirect the PPTP request to the local host
when enabled. Nat fails this attempt if Internet users initialize a
PPTP VPN request to a host located behind the router.
Multicast Enable
Optimizes the bandwidth utilization compared with unicast
(especially video streaming applications).
UPnP Enable
Activates Universal Plug and Play (UPnP) when enabled. A
UPnP device can dynamically join a network, obtain an IP
address, convey its capabilities, and learn about other devices
on the network. In turn, a device can leave a network smoothly
and automatically when it is no longer in use. Gaming
consoles and Web cameras are examples of devices that can
use UPnP.

DNS Relay
Allows the cable modem to act as the “relay” device. Each PC
that wants to access a URL does not have to send a DNS
request to a DNS server on the Internet. DNS is used to
resolve a URL (Web site name) to an IP address. DNS Relay
is typically used for commercial applications where each
device/PC connected to the cable modem uses the DNS Relay
address rather than going to a public DNS server hosted by an
ISP to look-up a URL.
NAT ALG Status
– Filters to allow (enable) or disallow (disable) protocols to pass through the
DVW3201B to connected devices (computers, game consoles, and so on).
RSVP
Enables or disables resource reservation protocol (RSVP).
RSVP defines how applications reserve resources and how
they free the reserved resources once they are no longer
needed.
FTP
Enables or disables the file transfer protocol (FTP) used to
transfer files from one host to another.
TFTP
Enables or disables the trivial file transfer protocol (TFTP) – a
simpler protocol generally used for automated file transfers.
Kerb88
Enables or disables the Kerberos network authentication
protocol which allow nodes to communicate over a non-secure
network using “tickets” on port 88 to prove their identity to one
another.
NetBios
Enables or disables the network basic input/output system
(NetBIOS) services related to the OSI session layer. NetBIOS
allows applications on separate computers to communicate
over a LAN.
IKE
Enables or disables the network key exchange (IKE) protocol
used to set up a security association (SA) in the IPsec protocol
suite.
RTSP
Enables or disables the real time streaming protocol (RTSP)
network control protocol used to establish and control media
sessions between end points.
Kerb1293
Enables or disables the Kerberos network authentication
protocol which allow nodes to communicate over a non-secure
network using “tickets” on port 1293.
H225
Enables or disables the H.225 protocol used to define
messages and procedures for call signalling, media
packetization, and registration, admission, and status (RAS)
functions.
PPTP
Enables or disables the point-to-point tunneling protocol
(PPTP) used to implement a virtual private network.
MSN
Enables or disables the Microsoft network protocol used for
instant messaging.

Using the Advanced Gateway Setup MAC Filtering Option
The
MAC Filtering
option allows you to filter MAC addresses to block Internet traffic from
specific network devices on the LAN. MAC filtering establishes a list and any host on this
list is not able to access the network through the DVW3201B.
Steps
To filter MAC addresses:
1.
Go to
Tools
>>
Client
List
. Your PC and other devices are listed. Note the MAC
address of the devices that you want to deny Internet access. For more information,
refer to
Using the Client List Option on page 83
.
Note:
Be sure all devices to which you potentially deny Internet access are connected
to the DVW3201B network.
2. Click the
Gateway
link from the top of the screen.
3. Click
MAC Filtering
from the left side of the screen. The
MAC Filtering
fields are
explained following this screen example.
SIP
Enables or disables the session initiation protocol application
layer gateway (SIP ALG). SIP ALG
inspects protocol
packets and formats SIP message headers and SDP
body to ensure proper signaling.
Note:
Some hosted VoIP
services prefer this function to be performed by their own
session border controller (SBC) and require the SIP ALG to be
disabled. Some IP-PBXs may require SIP ALG enabled.
ICQ
Enables or disables the ICQ instant messaging program.
IRC666x
Enables or disables the Internet relay chat (IRC) protocol used
for text messaging.
ICQTalk
Enables or disables the ICQTalk instant messaging program.
Net2Phone
Enables or disables Net2Phone SIP VoIP.
IRC7000
Enable or disables the Internet relay chat protocol on TCP port
TCP 7000 used for text messaging and group forums.
IRC8000
Enable or disables the Internet relay chat protocol on UDP port
8000 used for text messaging and group forums.
Apply
Saves all screen changes when clicked.

Using the Advanced Gateway Setup IP Filtering Option
The
IP Filtering
option allows you to filter IP addresses to block Internet traffic to specific
network devices on the LAN. Any host on this list is not accessible to Internet traffic.
5.8.1
Using IP Filtering Best Practices
The following are best practices to set up IP filtering.
1.
Make sure a PC is connected to the cable modem and both devices are powered on
and functioning.
2. Log in to the cable modem Web user interface. Refer to
Accessing the Web Interface
on page 17
.
3. Go to
Tools
>>
Client
List
. Your PC and other devices are listed. Note the MAC
address and IP address of the devices to which you want to deny Internet access. For
more information, refer to
Using the Client List Option on page 83
.
4. Go to
Gateway
>>
Static
Lease
. Enter the MAC address and IP address of devices to
Label
Description
Index
Assigns an index number to the rule.
MAC Address
Defines the MAC address to block.
Clear
Deletes the filtering rule when the Apply button is clicked and
the Clear box is checked.
View Additional Rules:
Displays rules 11-20 when selected from the drop-down list, if
they exist. A total of twenty rules are supported.

which you want to deny Internet access. Click
Apply
. For more information, refer to
Using the DHCP Static Lease Option on page 39
. A static lease ensures that the
device always gets the same IP address. That way, if filtered, it gets filtered
continuously. Otherwise, the IP address would change for the device and the filtering
rule would not work.
Note
You may also filter by the MAC address which does not require setting a static lease.
Refer to
Using the Advanced Gateway Setup MAC Filtering Option on page 44
.
Steps
To filter IP addresses:
1.
Click the
Gateway
link from the top of the screen.
2. Click
IP Filtering
from the left side of the screen. The
IP Filtering
fields are explained
following this screen example.
5.9
Using the Advanced Gateway Setup Port Filtering Option
The
Port Filtering
option allows you to configure port filters to block to all devices on the
LAN Internet services that use specific ports.
Label
Description
Start Address
Defines the starting IP address to filter.
End Address
Defines the ending IP address to filter.
Enabled
Activates the rule when enabled is checked.
Apply
Saves all screen changes when clicked.
