Wireless ADSL Router

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 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/.
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.
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.
