buttons below the table for adding, deleting, or modifying the static route entries. After making any change to the static routing table,
use APPLY or CANCEL to let the change take effect.
Advanced Setup | Routing | RIP
The router supports Routing Information Protocol (RIP) v1 and v2 to dynamically exchange routing information
with adjacent routers.
The RIP parameters are as follows:
- RIP mode - the operation mode. The overall RIP function can be enabled and disabled.
- Auto Summary - the automatic route merging. With this option, several routes to subnets under the same supernet can be replaced with a single route to that supernet in order to save routing table space.
- Operation Mode - the RIP functionality. The RIP function can be disabled (Disable), enabled for full function (Enable), or enabled for receiving only (Silent).
- Version - the RIP version. Both version 1 and 2 are supported.
- Poison Reverse - the Poison Reversion option. With this option the router will put routes learned from each neighbor into the updating RPDU with metric of 16 for better network convergence.
- Authentication Required - the RIP authentication. With RIP version 2, an authentication mechanism can be used to secure the routing exchange.
- Authentication Code - the RIP authentication key
The RIP mode and Auto Summary parameters apply globally; the other parameters apply to the network interface.
Advanced Setup | Routing | Routing Table
The run-time routing table.
Several types of route are supported. The Flag code identifies different types of routes:
- C - directly connected.
- R - RIP.
- I - ICMP redirect.
- S - static.
Advanced Setup | Firewall
The router provides a stateful inspection firewall which is designed to protect against
Denial of Service attacks when activated. Its purpose is to allow a private local area network (LAN)
to be securely connected to the Internet. It covers the following features:
1.Access control list - lets you define the traffic type permitted or not permitted for outgoing traffic. Users can specify the traffic type by network/session layer header such as port number or source or destination IP address.
2.Stateful Packet Inspection (SPI) - lets you specify the incoming traffic permitted or not permitted based on the application type such as TCP/UDP session, FTP session, or H.323 session.
3.Denial of Service (DoS) Attack prevention - defends and protects local network (LAN) resources against common attacks such as Ping fragment flood and SYN flood.
4.Real-time logging - lets you record the real-time firewall information for further use.
Advanced Setup | Firewall | Access Control
Access Control lets you define the outgoing traffic permitted or
not permitted for the WAN interface. The default is to permit all the outgoing
traffic. The rules defined under access control can limit access by different types of traffic. The router can also limit access by hosts within the local area network (LAN). The MAC Filtering Table lets you define up to 10 hosts that are not allowed to access to the WAN port.
Advanced Setup | Firewall | MAC Filter
This section helps provides MAC Filter configuration. When enabled, only MAC addresses configured will have access to your network. All other client devices will be denied access. This security feature can support up to 32 devices and applies to clients.
Advanced Setup | Firewall | URL Blocking
The router lets you block access to certain Web sites from a
particular PC by entering either a full URL address or a keyword of the
Web site. The router will examine all the HTTP packets to block the access to those
particular sites. This feature can be used to protect children from accessing
certain violent or sexual web sites.
Advanced Setup | Firewall | Schedule Rule
Each access control rule can be activated at a scheduled time. You can
define the schedule on the "Schedule Rule" page and apply the rule on the "Access Control" page.
Advanced Setup | Firewall | Intrusion Detection
Intrusion Dection includes two parts. One is Stateful Packet Inspection (SPI), and the other is Hacker Prevention.
Stateful Packet Inspection (SPI) limits the access
of the incoming traffic from the WAN port. When SPI is turned on, all
incoming packets will be blocked unless you select certain traffic types to be allowed. When you select a type of traffic, only that type of traffic initiated from Internal LAN will be allowed. For example, if
you only select "FTP service" on the Stateful Packet Inspection page, all
incoming traffic will be blocked except the FTP connection initiated from
the local LAN.
Hacker Prevention inspects packets at the application layer; maintains TCP and
UDP session information, including timeouts and number of active sessions;
and provides the ability to detect and prevent certain types of network attacks, such
as DoS attacks.
Network attacks that deny access to a network device are called denial-of-service
(DoS) attacks. Denial of Service (DoS) attacks are aimed at devices and networks
with a connection to the Internet. Their goal is not to steal information, but
to disable a device or network so users no longer have access to network resource.
The router's firewall provides protection from the following
DoS attacks: Ping of Death (Ping flood)
attack, SYN flood attack, IP fragment attack (Teardrop Attact), Brute-force
attack, Land Attack, IP Spoofing attack, IP with zero length, TCP null scan
(Port Scan Attack), UDP port loopback, Snork Attack etc..
Advanced Setup | Firewall | DMZ
If you have a client PC that cannot run an Internet application from
behind the NAT firewall, then you can open the client up to unrestricted
two-way Internet access.
Enter the IP address of a DMZ host on this page. Adding a client to the DMZ
(Demilitarized Zone) may expose your local network to a variety of security
risks, so only use this option as a last resort.
Advanced Setup | SNMP
The Simple Network Management Protocol (SNMP) is an application layer protocol
that facilitates the exchange of management information between network devices.
It is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite.
SNMP enables network administrators to manage network performance,
find and solve network problems, and plan for network growth.
Advanced Setup | UPnP
The Universal Plug and Play architecture provides pervasive peer-to-peer network connectivity to PCs of all form factors,
intelligent appliances, and wireless devices. UPnP enables seamless proximity networking in addition to control and data
transfer among networked devices in the home, in the office, and everywhere in between.
The router also supports MSN Messenger for systems without UPnP. You must enable the UPnP function to activate the
pass-through support.
Advanced Setup | ADSL
ADSL (Asymmetric Digital Subscriber Line) is used to deliver high-rate digital data over existing
ordinary phone lines. Using a new modulation technology called Discrete Multitone (DMT), ADSL facilitates
the simultaneous use of normal telephone services, ISDN, and high speed data transmission such as video.
Advanced Setup | ADSL | ADSL Parameters
This page allows you to specify the ADSL standards to use. You can set a specific
standard explicitly, or you can select "Automatic" to make the router automatically negotiate with remote DSLAM.
Advanced Setup | DDNS
Dynamic DNS (DDNS) is a system for allowing an Internet domain name to
be assigned to a varying IP address. This makes it possible for other
sites on the Internet to establish connections to the machine without
needing to track the IP address themselves. A common use is for running
server software on a computer that has a dynamic IP address (e.g., a dialup
connection where a new address is assigned at each connection, or a DSL
service where the address is changed by the ISP occasionally).
To implement Dynamic DNS it is necessary to set the maximum
caching time of the domain to an unusually short period (typically a few
minutes). This prevents other sites on the Internet from retaining the
old address in their cache, so that they will contact the name server
of the domain for each new connection. Some "client" programs
will, when installed, operate in the background and check the IP address
of the computer every few minutes. If it has changed, then it will send
an update request to the service.
The first step is to register with www.dyndns.org or www.tzo.com
to get an account. This is for people with a dynamic IP from their ISP
or DHCP server that would still like to have a domain name. The Dynamic
DNS service provider will provide you with a password or key to be entered
here.
The DDNS related parameters are described here;
- Dynamic DNS - Check Enable to use Dynamic DNS.
- Provider - This is the name of your Dynamic DNS service
provider.
- Domain Name - Type the domain name assigned to your wireless
base station by your Dynamic DNS provider.
- Account / E-mail - Enter your email address.
- Password / Key - Enter the password assigned to you.
Advanced Setup | Tools
This page includes the basic configuration tools, such as saving or restoring configuration settings or upgrading system firmware.

DHCP Dynamic Host Configuration Protocol. This protocol automatically
configures the TCP/IP settings of every computer on your home network.
DNS Server Address DNS stands for Domain Name System, which allows
Internet host computers to have a domain name and
one or more IP addresses. A DNS server keeps a database
of host computers and their respective domain names and IP addresses,
so that when a domain name is requested, the user is sent to the proper IP address.
The DNS server address used by the computers on your home network is the
location of the DNS server your ISP has assigned.
DSL Modem DSL stands for Digital Subscriber Line. A DSL modem
uses your existing phone lines to transmit data at high speeds.
Ethernet A standard for computer networks. Ethernet networks are
connected by special cables and hubs and move data at up to 10
million bits per second (Mbps).
