SHDSL VPN Firewall Bridge/Router 
 
Chapter 1: Introduction       
 
  
      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 Private Network (VPN)     
It allows user to make a tunnel with a remote site directly to secure the data transmission among 
the connection. User can use embedded PPTP and L2TP client/server, IKE and IPSec which are 
supported by this router to make a VPN connection or users 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. 
      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 
It supports web based GUI for configuration and management. It is user-friendly and comes with 
on-line help. It also supports remote management capability for remote users to configure and 
manage this product.
