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 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.
Firewall
Supports SOHO firewall with NAT technology. Automatically detects and blocks Denial of Service
(DoS) attacks. The URL blocking, packet filtering and SPI (Stateful Packet Inspection) are also
supported. The hacker’s attack will be recorded associated with timestamp in the security logging
area. More firewall functions will always be implemented through updated firmware releases.
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 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.
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 (“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.
