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. 
With this feature enabled, users can now connect to Net meeting or MSN Messenger seamlessly.  
 
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 
router’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.  
 
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.  
 
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.  
 
Firewall: Supports SOHO firewall with NAT technology. Automatically detects and blocks the Denial 
of Service (DoS) attack. Packet filtering is 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.  
 
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.  
 
Rich Packet Filtering: Not only filter the packet based on IP address, but also based on Port numbers 
and MAC address. It will increase the performance in LAN and WAN, also provide a higher-level 
security control  
 
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 and 
comes with on-line help. It also supports remote management capability for remote users to configure 
and manage this product.
