The HRDSL 740 router provides a high-speed ADSL port, a 4-port 10/100M Base-T Ethernet switch for high-speed Internet browsing. It can support downstream transmission rates of up to 8Mbps and upstream transmission rates of up to 1024Kbps. It also supports rate management that allows ADSL subscribers to select an Internet access speed suiting their needs and budgets. It is compliant with Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (G.992.1); G.lite (G992.2).
The product 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. Besides, an embedded PPTP client and PPTP server are supported to establish a VPN tunnel with a remote PPTP device. The product also supports VC-based and LLC-based multiplexing.
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 provides the natural firewall function (Network Address Translation, NAT), it also provides rich firewall features to secure a user'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 three levels of security support. First, it masks LAN users' 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, a user can open some specific ports for outside users to access internal services in the network. Finally it can also detect and block many Hacker Patterns and not allow hackers into your network.
Integrated DHCP services, client and server, allows up to 253 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 a local machine is powered up; the router will recognize it and assign an IP address to instantly connect it to the LAN.
For advanced users, The Virtual Server 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.

It also supports rate management that allows ADSL subscribers to select an Internet access speed suiting their needs and budgets. It is compliant with Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (G.992.1); G.lite (G992.2).
Fast Ethernet Switch: A 4-port 10/100Mbps fast Ethernet switch is supported in the LAN site and automatic switching between MDI and MDIX for 10Base-T and 100Base-TX ports is supported. An Ethernet straight or cross-over cable can be used directly, this fast Ethernet switch will detect it automatically.
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 the ISP. The product also supports VC-based and LLC-based multiplexing.
Quick Installation Wizard: Supports a WEB GUI page to install this device quickly. With this wizard, an end user can enter the information easily which they from the ISP, then surf the Internet immediately.
Universal
Plug and Play (UPnP) and UPnP NAT Traversal: This protocol is used to
enable simple and robust connectivity among stand-alone devices and PCs from
many different vendors. It makes network simple and affordable for users. UPnP
architecture leverages TCP/IP and the Web to enable seamless proximity
networking in addition to control and data transfer among networked devices.
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 gateways (ALG) are supported such as web browser, ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping, NetMeeting and others.
Firewall: Supports SOHO firewall with NAT technology. Automatically detects and blocks the Denial of Service (DoS) attack. The URL-blocking, packet filtering and SPI are also supported. The hacker's attack will be recorded associated with timestamp in the security logging area. More firewall features will be added continually, please visit our web site to download latest firmware.
Domain Name System (DNS) relay: provides an easy way to map the domain name (a friendly name for users such as www.yahoo.com) and IP address. When a local machine sets its DNS server with this router's IP address, then every DNS conversion requests packet from the PC to this router will be forwarded to the real DNS in the outside network. After the router gets the reply, then forwards it back to the PC.
Dynamic Domain Name
System (DDNS):
The Dynamic DNS service allows you to alias a dynamic IP address to a static
hostname. This dynamic IP address is the WAN IP address. For example, to use
the service, you must first apply an account from this free Web server http://www.dyndns.org/.
There are more than 5 DDNS servers supported.
Virtual Private Network (VPN): Allows a user to make a tunnel with a remote site directly to secure the data transmission among the connection. Users can use embedded PPTP client/server and IPSec supported by this router to make a VPN tunnel or the user can run the PPTP client in PC and the router already provides IPSec and PPTP pass through function to establish a VPN connection if the user likes to run the PPTP client in his local computer.
PPP over Ethernet (PPPoE): Provide 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 the local computer. The Always ON, Dial On Demand and auto disconnection (Idle Timer) functions are provided too.
Virtual
Server: Users 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, users can assign a PC in a LAN acting
as a WEB server inside and expose it to the outside network. Outside users can
browse an 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.
Rich Packet Filtering: Not only filters the packet based on IP address, but also based on Port numbers.
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 up to 253 client 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.
Static and RIP1/2 Routing: Supports an easy static table or RIP1/2 routing protocol to support routing capability.
SNTP: An easy way to get the network real time information from an SNTP server.
Web based GUI: supports web based GUI for configuration and management. It is user-friendly with an on-line help, providing necessary information and assist user timing. It also supports remote management capability for remote users to configure and manage this product.
Firmware Upgradeable: the device can be upgraded to the latest firmware through the WEB based GUI.

When you click this item, you get following sub-items to configure the ADSL router.
LAN, WAN, System, Firewall, VPN, Virtual Server and Advanced
These functions are described below in the following sections.
There are three items under the LAN section: Ethernet, Port Setting and DHCP Server. When you click Ethernet, you get the following figure.
It supports two Ethernet IP addresses in the LAN. With this function, the ADSL router can support two different LAN subnets to access the Internet at the same time. Usually, there is only one subnet in LAN, there is no need to configure a Secondary IP address. The 192.168.1.254 is the default IP address for this ADSL router. The Advanced Options will allow you to configure the routing protocol version1 or version 2 in receiving and sending direction.
When you click Port Setting, you get the following figure. This allows you to configure the port setting to solve some of the compatibility problems while connecting to the Internet.
Port # Connection Type: Five options to choose from: auto, 10M half-duplex, 10M full-duplex, 100M half-duplex or 100M full-duplex. Sometimes, there are Ethernet compatibility problems with legacy Ethernet devices. You can configure different types to solve the compatibility issues.
Port # Rate Limit: When it is enabled, enter a rate value that is configured as multiple of 32kbps. This function limits the inbound and outbound Ethernet throughput around the value that you specified.
TOS, Type of Services, is the 2nd
octet of IP packet. The bits 6-7
of this octet are reserved and bit 0-5 are used to specify the priority of the
packet.
IPv4 TOS priority Control: This feature uses bits 0-5 to classify the packets' priority. If the packet is in high priority, it will flow first and will not be constrained by the Rate Limit. Therefore, when this feature is enabled, the embedded Ethernet switch IC will check the 2nd octet of each IP packet. If the value in the TOS field matches in the checked values in the table (0 to 63), this packet will treat it as high priority.
When you click DHCP Server, you get the following figure. You can disable or enable the DHCP server or enable the DHCP relay functions.
If you check Disabled and click Next, then click Apply. The DHCP server function is disabled. Each PC in the LAN should assign a fixed IP address and set the PC's gateway to the ADSL router.
If you check DHCP Server and click Next, you can configure parameters of the DHCP server including the IP pool (starting IP address and ending IP address), leased time for each assigned IP address, DNS IP address, Gateway IP address. Those messages are sent to the DHCP client when it requests an IP address from the DHCP server. Click Apply to enable this function. If you check "Use Router as a DNS Server", the ADSL Router will find the IP address from the outside network automatically and forward it back to requesting PC in the LAN.
If
you check DHCP Relay Agent and click Next, then you will have to
enter the IP address of the DHCP server which will assign an IP address back to
the DHCP client in the LAN. Click Apply to enable this function.
There are two items under the WAN section, ISP and DNS. When you click ISP, you will get the following screen.
The factory default is RFC 1483 Routed Mode. If
your ISP uses the same access protocol, please click Edit to input other parameters as below. If your ISP does not use RFC 1483,
you can delete it, click Delete. Then you may click Create to create a connection to your ISP to surf the Internet. Refer to the

is a short cut to the Quick Start
page.
The WAN-DNS is shown as below.
A Domain Name System (DNS)
contains a mapping table for domain name and IP addresses. In the Internet,
every host has a unique and friendly name such as www.yahoo.com
and an IP address. As the IP Address is hard to remember, the DNS converts the
friendly name into its equivalent IP Address.
You can obtain a Domain Name
System (DNS) IP address automatically if your ISP has provided it when you
logon. Usually when you choose PPPoE or PPPoA as your WAN - ISP protocol, the
ISP will provide the DNS IP address automatically. You may leave it as blank. Or
your ISP may provide you with an IP address of their DNS. If this is the case,
you must enter the DNS IP address.
If you choose one of the other three protocols ¢w RFC1483
routed /bridged and IPoA. Check with
your ISP, it may provide you with an IP address of DNS. You must enter the DNS
IP address if you set the DNS of your PC to the LAN IP address of this router.
There are six items under the System section: Time Zone, Remote Access, Firmware Upgrade, Backup/Restore, Restart Router and User Management.
When you click Time Zone, you get the following figure.
The router does not have a real time clock on board; instead, it uses the simple network time protocol (SNTP) to get the current time from the SNTP server from the outside network. Please choose your local time zone, click Enable and click the Apply button. You will get the correct time information after you ready establish a connection to the Internet. If you prefer to enter your own SNTP server, please enter and use it as the first choice.
Resync Poll Interval (in minutes) is the periodical interval of router's SNTP client to update (or re-synchronize) the current time with SNTP server after it synchronized with SNTP server.
When you click Remote Access and then
click Enable, you may temporarily permit remote administration of the HRDSL
740 ADSL Firewall Router.
When you click Firmware Upgrade, it allows
you to input the location of firmware stored on your PC and click the Upgrade
button to upgrade to the new firmware.
When you click Backup/Restore, it allows
you to save your current settings into a file on your PC. If you like to
restore it back (input the location of this configuration file in the PC and
click the Restore button to save it back).
When you click Restart Router, you have two functions. One is to restart it with current settings and
the other is to restart it with factory default settings if you check Reset to factory default settings.
When you click User Management, you are
able to edit existing user's database or to create other user accessing this
device.
There are five items under the Firewall section: General Settings, Packet Filter, Intrusion Detection, MAC Address Filter and URL Filter.
When you click General Settings, you get the following figure.
Firewall: When you enable the Firewall function, you can select one of the firewall security policies. By default the firewall is set to disabled.
All blocked/User-defined: By default, all traffic between WAN and LAN are blocked. You have to configure the type of traffic passed between WAN and LAN, please refer to Packet Filter below.
High, Medium and Low security level: By default, your system uses High, Medium and Low firewall security levels between the WAN and LAN. For example, when you select High, the Port Filters of the Packet Filter screen will be set automatically according to High security level settings.
Firewall
Logging: When both the Firewall Security and Firewall Logging are enabled,
the device will detect the blocked and/or intrusion packets, once the setting
has been configured. Then the
router will log the corresponding (blocking or intrusion detection) logs into
the Event Log under Status.
Select the Apply button to save the setting.
When you click Packet Filter, you get the following figure.
You may configure to filter inbound (incoming) and outbound (outgoing) packets based on PORT or IP address.
If it is based on PORT, click Port Filters for more options. You may filter the packets based on PORT and packet type (TCP or UDP or any). For example, the protocol number 1 means ICMP. You may enter 1 to protocol number of Raw IP Filtering web page. Port ranges are supported.
If it is based on IP address, click Address Filters for more options. You may enter the IP address and again to select the inbound or outbound packets.
For example, to allow TCP packet, port 0 to 1000 passing router between WAN and LAN and blocks host IP address, 192.168.1.100. Then you have to configure the port filter à add TCP filter > 0 to 1000 and ALLOW in both direction. Then click address filter à add address filter à enter host IP 192.168.1.100, subnet mask 255.255.255.255 (for this single host) and both direction.

Keyword Filtering:
The ADSL Router allows the administrator to block some WEB URLs containing certain keywords in this page. For example, if the keyword "xxx" is listed, the URL http://www.new.site.com/xxx.html would be blocked, even if it is not included in the domain filtering list. Keywords presented as site name are also blocked; that is, http://www.xxxsite.com cannot be accessed from the LAN.
To add a keyword, enter it in the Keyword
field and click Apply.
Domain Filtering:
If the router is configured to allow internal users to access only certain specified domains, check add the domain name into the Trusted Domain list. If the router is configured to allow internal users to access all websites except for some forbidden domains, add the forbidden domain name into the Forbidden Domain list. These Forbidden Domains will be blocked, and users will no longer be able to access the websites from the LAN.
To add a domain name, enter its host name, such as www.bad-site.com into the text field under Domain and select either Trusted Domain or Forbidden Domain, then click Apply. The specified domain will be shown in the Domain List. DO NOT include http://, ONLY the sub-domain is allowed. For instance, taking "yahoo.com" as the trusted domain means that www.yahoo.com, my.yahoo.com, and sports.yahoo.com will also be trusted.
To remove a site that was previously added, select its name in the list box, and click the Delete button to eliminate it from the list.

the local host.
¤
Subnet: The subnet of the local
network. For example, IP: 192.168.1.0 with netmask 255.255.255.0 specifies one
class C subnet starting from 192.168.1.1.
¤
IP Range: The IP address range of the local network. For
example, IP: 192.168.1.1, end IP: 192.168.1.10
Remote
Secure Gateway Address (or hostname): The IP address or hostname of remote VPN device that is connected and establishes a VPN tunnel
Network: Set the IP address, subnet or address range of the remote network.
Proposal: Select the IPSec security method. Check ESP for a higher security, data will be encrypted and authenticated. Check AH, data will be authenticated but not encrypted.
Authentication: There are three options, MD5, SHA1 or NONE. Authenticate the data using MD5, SHA1 or NONE.
Encryption: Select the encryption method. The DES uses 56 bits as an encryption method. The 3DES uses 168 (56*3) bits as an encryption method. The AES uses 128 bits as an encryption method. The NONE means it is a tunnel only, no encryption.
Perfect Forward Secrecy: Enable this to change encryption keys during the second phase of VPN negotiation. This function will provide better security, but extends the VPN negotiation time.
Pre-shared Key: This is a string from 4 characters to 128 characters. Both sides should use the same key.
Click Advanced Option to get the following figure.
SA Lifetime: Specify the number of minutes that a VPN tunnel will stay active before new encryption and authentication key will be exchanged. The SA Lifetime may range from 10 to 10,000 minutes.
Phase
1 (IKE): To issue an initial connection request for a new VPN tunnel. Default
240 minutes, range from 5 to 15,000 minutes.
Phase
2 (IPSec): To negotiate and establish secure authentication. Default 60
minutes, range from 5 to 15,000 minutes.
Select the Change button to update the setting.
When you click Virtual Server, you get the following
figure.
Being a natural Internet firewall, this network
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 modem can act as a virtual server.
You can set up a local server with specific a port number that stands for the
service, e.g. Web (80), FTP (21), Telnet (23), SMTP (25), POP3 (110), When an
incoming access request to the router for a specified port is received, it will
be forwarded to the corresponding internal server.
For example, if you set the Service Port number
80 (Web) to be mapped to the IP Address 192.168.1.2, then all the http requests
from outside users will be forwarded to the local server with IP address of
192.168.1.2. If the port is not listed as a predefined application, you need to
add it manually.
DMZ: The DMZ Host is a local computer exposed to the Internet. Therefore, an
incoming packet will be checked by the Firewall and NAT algorithms, then passed
to the DMZ host when a packet is not sent by a hacker and not limited by the
virtual server list.
|
|
If you have disabled
the NAT option in the WAN-ISP section, this Virtual Server function will
hence be invalid. |
|
|
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 can configure the
virtual server IP address manually, but it is still in the same subnet with
the router. |
There are four items under the Advanced section: Routing
Table, Dynamic DNS, Checking Email and Device Management.
Click on the Routing Table and then choose Create Route to get the below figure to add a routing table.
Destination: Enter the destination subnet IP.
Netmask: Subnet mask of destination IP addresses based
on above destination subnet IP.
Gateway: Enter the gateway IP address which the packet
is forwarded to.
Interface: Enter the interface which the packet is forwarded to.
Cost: This is the same meaning as Hop. Usually,
leave it as 1.
Click Dynamic DNS to get the below figure then check the "Enable" button to access the Dynamic DNS service.
The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname. This dynamic IP address is the WAN IP address. For example, to use the service, you must first apply for an account from this free Web server http://www.dyndns.org/. There are more than 5 DDNS servers supported.
Dynamic DNS: Select the registered DDNS server.
Domain Name, Username and Password: Enter the registered domain name, username
and password.
Period: Set the time period for the Router to
exchange information with the DDNS server. In addition to update periodically
according to this period setting, the Router will take the same action automatically
whenever the assigned IP changes.
Click Checking
Email to get the below figure then check the "Enable" button to access the
service.
¤ Disable: Check to disable the ADSL router from getting the email.
¤ Enable: Check to enable the ADSL router to get the email by providing the required information. Hence, the following fields will be activated and required.
Account Name: Enter the name of the account to which you have the POP access. Normally, it is the text in your email address before the "@" symbol. If you have trouble with it, please contact your ISP.
Password: Enter the password of the account
POP3
Mail Server: Enter your (POP) mail server name. If you have trouble with it, you would want to contact your
ISP or your external mail server's administrator. For further assistance in
tracking down this information, you will need to contact your Internet Service
Provider or Network Administrator.
Interval: Enter the value in minutes to check your email account periodically.
Automatically dial-out for checking emails: When the function is enabled, your ADSL router will connect to your ISP automatically to check emails if your Internet connection dropped. Please be careful when using this feature if your ADSL service is charged by time.
Click Device Management to protect and obtain system control while allowing device monitoring. This in turn provides enhanced security of the device.
Embedded
Web Server
HTTP Port: Default value for HTTP port is 80. A desired value is also allowed. Simply specify a user-defined port number.
Management IP Address: Specify an IP address allowed to logon and access the router's web server.. Note: IP 0.0.0.0 indicates all users who are connected to this router are allowed to logon the device and modify data. ]
Expire to auto-logout: Specify a time frame for the system to auto-logout the device.
For Example: User A changes HTTP port number to 100, specified it's own IP address to be 192.168.1.55, and set the logout time to be 100 seconds. Device will only allow User A which IP address is 192.168.1.55 to logon to the Web GUI by typing: 192.168.1.254:100. After 100seconds, the device will automatically logout User A.
Universal
Plug and Play (UPnP)
¤ Disable: Check to disable UPnP function.
¤ Enable: Check to enable UPnP function.
UPnP Port: Its default setting is 2800. It is highly recommended for users to use this port value. You may wish to modify this port value, only if this value conflicts with other ports already being used.
SNMP Access Control (downloading SNMP software is required in order to utilize this section)
Read Community: Specify a name in any string to be identified as the Read Community and an IP address. This community string will be checked against the string entered in the configuration file. Once the string name is matched, user obtains this IP address will be able to view the data.
Write Community: Specify a name in any string to be identified as the Write Community and an IP address. This community string will be checked against the string entered in the configuration file. Once the string name is matched, user obtains this IP address will be able to view and modify the data.
Trap Community: Specify a name in any string to be identified as the Trap Community and an IP address. This community string will be checked against the string entered in the configuration file. Once the string name is matched, user obtains this IP address will be notified Traps.
After configuring this network router, you have to save all of the configuration parameters to FLASH.
To exit the website, choose Logout to exit completely. Please ensure that you have saved the configuration settings before logout.
Be aware that the router is restricted to only one local PC accessing the configuration Web pages. Once a current PC has logged onto the Web pages, other PCs cannot get access except waiting for the current PC to log out of the page. If the previous PC forgets to logout, the second PC can access the page after 3 minutes.
If the ADSL Router is not functioning properly, you can refer first to this chapter for simple troubleshooting before contacting your service provider. This could save you time and effort but if the symptoms persist, then consult your service provider.
