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 simple firewall with NAT technology and provides option for blocking access from
Internet, like Telnet, FTP, WEB, SNMP and IGMP.
Domain Name System (DNS) relay
Provide 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/.
PPP over Ethernet (PPPoE)
Provide 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.
