VoIP/(802.11g) Broadband Firewall Router 
 
Chapter 1: Introduction       
 
  
      Network Address Translation (NAT) 
Allows multi-users to access outside resources such as the Internet simultaneously with one IP 
address/one Internet access account. Many application layer gateway (ALG) are supported such as 
web browser, ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping, NetMeeting, IP phone and others. 
      SOHO Firewall Security with DoS and SPI 
Along with the built-in NAT natural firewall feature, the router also provides advanced hacker 
pattern-filtering protection. It can automatically detect and block Denial of Service (DoS) attacks. 
The router is built with Stateful Packet Inspection (SPI) to determine if a data packet is allowed 
through the firewall to the private LAN.     
      Domain Name System (DNS) relay   
 It 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, every DNS conversion request packet from the PC to this router will be forwarded to the 
real DNS in the outside network.   
      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 for 
an account from a DDNS service like http://www.dyndns.org/. More than 5 DDNS servers are 
supported. 
 
Quality of Service (QoS)   
QoS gives you full control over which types of outgoing data traffic should be given priority by the 
router, ensuring important data like gaming packets, customer information, or management 
information move through the router ay lightning speed, even under heavy load. The QoS features 
are configurable by source IP address, destination IP address, protocol, and port. You can throttle 
the speed at which different types of outgoing data pass through the router, to ensure P2P users 
don’t saturate upload bandwidth, or office browsing doesn’t bring client web serving to a halt. In 
addition, or alternatively, you can simply change the priority of different types of upload data and let 
the router sort out the actual speeds.   
      Virtual Server (“port forwarding”) 
Users can specify some services to be visible from outside users. The router can detect incoming 
service requests and forward either a single port or a range of ports to the specific local computer to 
handle it. For example, a user can assign a PC in the LAN acting as a WEB server inside and 
expose it to the outside network. Outside users can browse inside web servers 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. It will filter packets 
from and to the Internet, and also provides a higher level of security control. 
      Dynamic Host Configuration Protocol (DHCP) client and server 
In the WAN site, the DHCP client can get an IP address from the Internet Service Provider (ISP) 
automatically. In the LAN site, the DHCP server can allocate a range of 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 
 
    It has routing capability and supports easy static routing table or RIP1/2 routing protocol.   
      Simple Network Management Protocol (SNMP) 
   It is an easy way to remotely manage the router via SNMP. 
      Web based GUI
