Chapter 1: Introduction
1.1 An Overview of the ADSL Router
The ADSL Router provides a high-speed ADSL port and an Ethernet port for high-speed Internet browsing. It can support
downstream transmission rates of up to 8Mbps and upstream transmission rates of up to 1024Kbps. It also supports rate
management that allows ADSL subscribers to select an Internet access speed suiting their needs and budgets. It is
compliant with Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt(G.992.1); G.lite(G992.2)).
The product supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483 encapsulation over ATM (bridged
or routed), PPP over Ethernet (RFC 2516), IPoA (RFC1577) and PPTP-to-PPPoA relaying to establish a connection with ISP.
Besides, an embedded PPTP client is supported to establish a VPN connection with remote PPTP server. The product also
supports VC-based and LLC-based multiplexing.
It is the perfect solution to connect a small group of PCs to a high-speed broadband Internet connection. Multi-users can
have high-speed Internet access simultaneously.
This product also serves as an Internet firewall, protecting your network from being accessed by outside users. Not only
provide the natural firewall function (Network Address Translation, NAT), it also provides rich firewall features to secure
user’s network. All incoming data packets are monitored and filtered. Besides, it can also be configured to block internal
users from accessing to the Internet.
The product provides three levels of security support. First, it masks LAN users’ IP addresses which are invisible to outside
users on the Internet, making it much more difficult for a hacker to target a machine on your network. Secondly it can block
and redirect certain ports to limit the services that outside users can access. For example, to ensure that games and other
Internet applications will run properly, user can open some specific ports for outside users to access internal services in
network. Finally it can also detect and block many Hacker Patterns and not allow hacker into your network.
Integrated DHCP services, client and server, allow up to 253 users to get their IP addresses automatically on boot up from
the product. Simply set local machines as a DHCP client to accept a dynamically assigned IP address from DHCP server
and reboot. Each time local machine is powered up; the router will recognize it and assign an IP address to instantly connect
it to the LAN.
For advanced users, Virtual Service function allows the product to provide limited visibility to local machines with specific
services for outside users. An ISP provided IP address can be set to the product and then specific services can be rerouted
to specific computers on the local network. For instance, a dedicated web server can be connected to the Internet via the
product and then incoming requests for HTML that are received by the product can be rerouted to the dedicated local web
server, even though the server now has a different IP address. In this example, the product is on the Internet and vulnerable
to attacks, but the server is protected.
Virtual Service can also be used to re-task services to multiple servers. For instance, the product can be set to allow
separated FTP, Web, and Multiplayer game servers to share the same Internet-visible IP address while still protecting the
servers and LAN users from hackers.
