The DC214/216ADSL
Modem provides a high-speed Ethernet port and an USB port for high-speed Internet
browsing. It can support downstream transmission rates of up to 8Mbps and
upstream transmission rates of up to 1024Kbps. It is compliant with Multi-Mode standard
(ANSI T1.413, Issue 2; G.dmt (G.992.1); G.lite (G992.2); G.hs (G994.1)).
It is
the perfect solution to connect a small group of PCs to a high-speed broadband
Internet connection. Multi-users can have high-speed Internet access
simultaneously.
This
product also serves as an Internet firewall, protecting your network from being
accessed by outside users. Not only provide the natural firewall function
(Network Address Translation, NAT), it also provides rich firewall features to
secure userˇ¦s network. All incoming data packets are monitored and filtered. Besides, it can also be configured to block
internal users from accessing to the Internet.
The product provides two levels of security
support. First, it masks LAN usersˇ¦
IP addresses which are invisible to outside users on the Internet, making it
much more difficult for a hacker to target a machine on your network. Secondly, it can block and redirect
certain ports to limit the services that outside users can access. For example, to ensure that games and
other Internet applications will run properly, users can open some specific ports
for outside users to access internal services in network.
Integrated
DHCP services, client and server, allow multiple users to get their IP
addresses automatically on boot up from the product. Simply set local machines as a DHCP
client to accept a dynamically assigned IP address from DHCP server and
reboot. Each time local machine is
powered up; the router will recognize it and assign an IP address and instantly
connect it to the LAN.
For advanced users, the Virtual Service function allows the product
to provide limited visibility to local machines with specific services for
outside users. An ISP provided IP
address can be set to the product and then specific services can be rerouted to
specific computers on the local network.
For instance, a dedicated web server can be connected to the Internet
via the product and then incoming requests for HTML that are received by the
product can be rerouted to the dedicated local web server, even though the
server now has a different IP address.
In this example, the product is on the Internet and vulnerable to
attacks, but the server is protected.
Virtual Server can also be used to re-task services to
multiple servers. For instance, the
product can be set to allow separated FTP, Web, and Multiplayer game servers to
share the same Internet-visible IP address while still protecting the servers
and LAN users from hackers.

The
DC214/216ADSL Modem provides the following features:
ADSL
Multi-Mode Standard: Supports downstream transmission rates of up to 8Mbps and upstream
transmission rates of up to 1024Kbps. It is compliant with Multi-Mode standard
(ANSI T1.413, Issue 2; G.dmt (G.992.1); G.lite (G992.2); G.hs (G994.1)).
Multi-Protocol
to Establish A Connection: Supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer
5), RFC 1483 encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC
2516) and IPoA (RFC1577) to establish a connection with ISP. The product also
supports VC-based and LLC-based multiplexing.
Network
Address Translation (NAT): Allows multi-users to access outside resource such as
Internet simultaneously with one IP address/one Internet access account.
Besides, many application layer gateway (ALG) are supported such as web
browser, ICQ, FTP, Telnet, E-mail, News, Ping and others.
Domain Name System
(DNS) relay: Provides an easy way to map the domain name (a friendly name for
user such as www.yahoo.com)
and IP address. When local machine sets its DNS server with this routerˇ¦s IP
address. Then every DNS conversion request packet from the PC to this router
will be forwarded to the real DNS in outside network. After the router gets the
reply, then forwards it back to the PC.
PPP over Ethernet
(PPPoE): Provides embedded PPPoE client function to establish a connection.
Users can get greater access speed without changing the operation concept,
sharing the same ISP account and paying for one access account. No PPPoE client
software is required for local computer. The Automatic Reconnect and Disconnect
Timeout (Idle Timer) functions are provided, too.
Virtual
Server: User can specify some services to be visible from outside users.
The router can detect incoming service request and forward it to the specific
local computer to handle it. For example, user can assign a PC in LAN acting as
WEB server inside and expose it to the outside network. Outside user can browse
inside web server directly while it is protected by NAT. A DMZ host
setting is also provided to a local
computer exposed to the outside network, Internet.
Bridge
Filtering: Filters the packet based on MAC address. It will increase the
performance in LAN and WAN, also provide a higher-level security control.
Dynamic
Host Control Protocol (DHCP) client and server: In the WAN site, the
DHCP client can get an IP address from the Internet Server Provider (ISP)
automatically. In the LAN site, the DHCP server can allocate multiple clients
IP addresses and distribute them including IP address, subnet mask as well as
DNS IP address to local computers. It provides an easy way to manage the local
IP network.
Web based GUI: Supports
user-friendly web based GUI for configuration and management.

The NAT Configuration page allows the user to set the configuration
for the Network
Address Translation. NAT feature allows
multiple users to access Internet through a single IP account, sharing the
single IP address from ISP.
The default setting is Dynamic NAPT. It provides dynamic Network
Address Translation capability between LAN and multiple WAN connections, and
the LAN traffic is routed to appropriate WAN connections based on the
destination IP addresses and Route Table. This eliminates the need for the
static NAT session configuration between multiple LAN clients and multiple WAN
connections. When the Dynamic NAPT is chosen, there is no need to configure the
NAT Session and NAT Session Name Configuration.
The NAT option only
maps single WAN IP address to the local PC IP address. It is peer to-
peer mapping. (1x1) For each WAN interface, only one local PC IP address
can be
associated with each WAN interface. Click the link Session Name
Configuration to add
the session name for WAN interface.
The NAPT option maps the single WAN IP addresses to many local PCs
IP addresses.
(1xN). It is the multiple-mapping mechanism. For each WAN Interface, more
than one
local PCs can be associated with one WAN Interface. Click the link Session
Name
Configuration to add the session name for WAN interface.

Being
a natural Internet firewall, the ADSL Router protects your network from being
accessed by outside users. When it needs to allow outside users to access
internal servers, e.g. Web server, FTP server, E-mail server or News server,
this product can act as a virtual server. You can set up a local server with
specific port numbers that stands for the service, e.g. Web (80), FTP (21),
Telnet (23), SMTP (25), POP3 (110), DNS (53), ECHO (7), NNTP (119). When an
incoming access request to the router for specified port is received, it will
be forwarded to the corresponding internal server.
For
example, if you set the Public Port number 21 (FTP) to be mapped to the IP
Address 192.168.1.100, then all the ftp requests from outside users will be
forwarded to the local server with IP address of 192.168.1.100.

Public Port: Enter the public port number you want to configure.
Private Port:
Enter the private port number you want to configure. In most cases, the private
port number is same as public port number.
Port Type: Select TCP if you want to scope for the
connection-based application service on the remote server using the port number. Or select UDP if you
want to scope for the connectionless application service on the remote server using the port number.
Host IP Address: Enter the IP address of certain
internal server to which requests from the specified port is forwarded.
|
|
If the DHCP server option is enabled, you have to be
very careful in assigning the IP addresses of the virtual servers in order to
avoid conflicts. The easy way is that the IP address assigned to each virtual
server should not fall into the range of IP addresses that are to be issued
by the DHCP server. You configure the virtual server IP address manually, but
it is still in the same subnet with the router. |
The Bridge Filtering configuration page allows the user to set the
configuration of IP
filtering.

Source MAC: When the bridge filtering is enabled, enter the Source MAC address,
select Block and click Add. Then all incoming WAN and LAN
Ethernet packets matched
with this source MAC address will be filtered out. If the Forward is
selected, then the
packets will be forwarded to the destination PC.
Destination MAC: When the bridge filtering is
enabled, enter the Destination MAC
address, select Block and click Add. Then all incoming WAN and LAN
Ethernet
packets matched with this destination MAC address will be filtered out. If
the Forward
is selected, then the packets will be forwarded to the destination PC.
Type: Enter the hexadecimal number
for the Ethernet type field in Ethernet_II packets.
For example, 0800 is for IP protocol.
The DNS Configuration page allows the user to set the configuration
of DNS proxy.
The firmware supports the DNS proxy function. For the DHCP requests from
local PCs, the DHCP server will set the LAN port IP as the default DNS
server. Thus, all
DNS query messages will come into LAN port first. The DNS proxy on the ADSL
modem recorded the available DNS servers, and forward DNS query messages to
one of
DNS
server.

Disable DNS Proxy: The LAN port does not process the DNS query message. For the
DHCP requests from local PCs, the DHCP server will set the user-configured
preferred
DNS sever or alternate DNS server whichever is available as the DNS server.
Then all
DNS query messages will be directly sent to the DNS servers.
Use Auto Discovered DNS
Servers Only: The DNS proxy will store the DNS server IP
addresses obtained from DHCP client or PPP into the table. And all DNS
query messages
will be sent to one of the dynamically obtained DNS servers.
Use User Configured DNS
Servers Only: The DNS proxy will use the user-configured
preferred DNS server and alternate DNS server. And all DNS query message
will be sent
to one of DNS servers. Enter the DNS IP in the Preferred DNS Server and Alternate
DNS
Server fields.
Auto Discovery + User
Configured: The DNS proxyˇ¦s table has all the IP addresses of
dynamically obtained and user configured DNS servers.

Click

The Route Table page displays routing table and allows the user to
manually enter the
routing entry. The routing table will display the routing status of
Destination, Netmask,
Gateway, and Interface. The interface br0 means the USB interface; lo0
means the
loopback interface; and ppp1 means the PPP interface. The Gateway is the
learned
Gateway

New Enhancement for
Routing Table
• The Gateway field of the static route entry allows users to either enter
a Gateway IP
address or select a Network Interface.
• All user-defined routes retained in the CPE memory, regardless if they
are already in the
Routing Table, are displayed on the same Route Table page.
• All user defined route entries kept in the CPE memory during run time are
saved to flash
when the user chooses to save and reboot the CPE. When CPE restarts, it
reloads all
saved user-defined routes to the CPE memory and tries to apply to the
system.
• A user-defined route entry is added to the Routing Table whenever the system
provides
an environment that makes the route entry applicable. It is removed from
the Routing
Table whenever the route entry becomes not applicable. e.g. If the route
entryˇ¦s Gateway
is associated with a dynamic Network Interface but the connection is not
established, then
the route entry does not appear in the Routing Table. When that interface
comes up later,
the route entry is then added.
• If the selected Network Interface is static or is dynamic and the
connection is already up,
then the route entry appears in the Routing Table immediately. If there is
a Gateway
associated with the selected Network Interface, then that Gatewayˇ¦s IP
address appears in
the Gateway field of the route entry
• If the selected Network Interface is dynamic but the connection is not
established, then
the route entry does not appear in the Routing Table. When the interface
comes up later,
the route entry is then added.
System Default Gateway
Configuration
The system-wide Default Gateway now provides three options: Auto,
User-selected
Network Interface, and None.
None: This field allows the user to
choose to have no Default Gateway in the CPE
Auto: This field allows the user to
select the CPE to automatically decide the Default
Gateway. (System Default)
User-selected Network
Interface: This field allows user to select a Network Interface
from a list (PVCs, PPP Sessions, USB and LAN). This option lets the user to
associate
the system-wide Default Gateway to a Network Interface, static or dynamic,
and provides
a way to fix the Default Gateway to a dynamic Network Interface before the
interface is
established.
Route Configuration
Destination: This field allows the user to enter the remote network or host IP address
for
the static routing.
Netmask: This field allows the user to
enter the Subnet Mask for the static routing.
Gateway: This field allows the user to
enter the IP address of the gateway device that
allows the router to contact the remote network or the host for Specified
IP or select an
Interface for the Gateway.
Manually Configured Routes: This field displays the static
route entries entered by the user

Aging Timeout: Enter the time period for the
router to memorize MAC addresses.

T1.413, G.dmt, G.lite.
Wiring Selection: Default at Tip/Ring. Select Auto or A/A1
if necessary.
Bit Swapping: This field allows the user to enable or disable the upstream bit swapping.
The Routing Information
Protocol, enables routers to broadcast and receive information to and
from other routers about which routers itˇ¦s connected and the steps it requires
to get there. A router will changes itˇ¦s routing table if it receives
information it could reach a specific router faster.

RIP: This field allows the user to Enable or Disable the RIP session. The
resulting RIP
session will monitor all network interfaces that are currently available
for messages from
other RIP routers.
Supplier Interval: This field allows the user to
enter the Supplier Interval timer in
second. This timer specifies how often RIP sends announcements as a RIP
Supplier.
(Default = 30 seconds)
Expire Timeout: This field allows the user to
enter the Expire timer in second. This
timer specifies the expiration time of a route. When a route has not been
updated for
more than ˇ§expireˇ¨ period of time, it is removed from the Route Table. This
route is
invalidated and remains in the internal
announcements to let other routers know the changes. (Default = 180
seconds)
Garbage Timeout: This field allows the user to
enter the Garbage timer in second. This
timer specifies how long the expired and invalidated routes are kept in the
Internal RIP
Route Table before it is removed from it. (Default = 300 seconds)
The RIP Per Interface Configuration
page allows the user to set the configuration for each Interface (PVCs, PPP
Sessions, USB and LAN).
Interface: This field allows the user to
choose the Interface (PVCs, PPP Sessions, USB
and LAN), for the RIP to be configured.
Enable: This field allows the user to
Enable (Yes) or Disable (No) the specified
interface for RIP.
Supplier: This field allows the user to
select the Supplier Mode (RIP Transmit).
• Disabled: The supplier transmit is disabled.
• V1 BC: The supplier transmits in RIPv1 Broadcast.
• V2 BC: The supplier transmits in RIPv2 Broadcast.
• V2 MC: The supplier transmits in RIPv2 Multicast.
Listener: This field allows the user to
select the Listener Mode (RIP Receive)
• V1: The listener receives the RIPv1 only.
• V2: The listener receives the RIPv2 only.
• V1+V2: This listener receives the both RIPv1 and RIPv2.
Supplier and Listener are based on section 4.1 ˇ§Compatibility Switchˇ¨ in
RFC 1723.
Current RIP Settings: This field displays the each
interfaceˇ¦s RIP status.

In factory setting, the default password for administrator
is password, and that for user is also password. You can change the default
password to ensure that someone cannot adjust your settings without your
permission. Every time you change your password, please record the password and
keep it at a safe place.
Please note that the minimum input for password is 8
alphanumeric characters. Since it is case sensitive, be sure that you
remember whether a letter is in upper or lower case and make sure that your
Caps Lock is off. Moreover, please do not use the sign ˇ§&ˇ¨ in the
passwords.

http://192.168.1.254:1001.
FTP server: This field allows the user to
enable or disable the FTP connection.
TFTP server: This field allows the user to
enable or disable the TFTP connection.
DMZ: A DMZ (De-Militarized Zone) is
added between a protected network and an
external network, in order to provide an additional layer of security. When
there is a
suspected packet coming from WAN, the firewall will forward this packet to
the DMZ
host.
DMZ Host IP: The IP address of the DMZ host
at LAN side.
DHCP Relay: If it is enabled, the DHCP
requests from local PCs will forward to the
DHCP server runs on WAN side. To have this function working properly,
please disable
the NAT to run on router mode only, disable the DHCP server on the LAN
port, and
make sure the routing table has the correct routing entry.
DHCP Target IP: The DHCP server runs on WAN
side.
IGMP Proxy: Here is the global setting for
IGMP Proxy. If it is enabled, then the
enabled IGMP Proxy on WAN PVCs will be working. Otherwise, no WAN PVC can
have IGMP Proxy working on it.
PPP connect on WAN access: If it is enabled, the PPP session
will be automatically
established when there is a packet wants to go out the WAN.
the Internet, and the DHCP server will duplicate the WAN IP address from
the ISP to the
local client PC. Only the PC with the WAN IP address can access the
Internet.

With the submit button, the router will be reset to itˇ¦s
default settings, described in chapter 5.1. Be carefull, all your settings will
be lost.
