Chapter 1: Introduction

Introduction to your Router

Thank you for purchasing BEC 7800 Router. Your new router is an all-in-one unit that combines an

ADSL modem, ADSL2/2+ router and Ethernet network switch to provide everything you need to

get the machines on your network connected to the Internet over an ADSL broadband connection.

The BEC 7800 router complies with ADSL2+ standards for deployment worldwide and supports

downstream rates of up to 24 Mbps and upstream rates of up to 1 Mbps. Designed for small office,

home office and residential users, the router enables even faster Internet connections. You can

enjoy ADSL services and broadband multimedia applications such as interactive gaming, video

streaming and real-time audio much easier and faster than ever before.

The BEC 7800 supports PPPoA (RFC 2364 – PPP (Point-to-Point Protocol) over ATM Adaptation

Layer 5), RFC 1483 encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516)

to establish a connection with your ISP. Your new router also supports VC-based and LLC-based

multiplexing.

The perfect solution for connecting a small group of PCs to a high-speed broadband Internet

connection, the BEC 7800 allows multiple users to have high-speed Internet access

simultaneously.

Your new router also serves as an Internet firewall, protecting your network from access by

outside users. Not only does it provide a natural firewall function with Network Address Translation

(NAT), it also provides rich firewall features to secure your network. All incoming data packets

are monitored and filtered. You can also configure your new router to block internal users from

accessing the Internet.

The BEC 7800 provides two levels of security support. First, it masks LAN IP addresses making

them invisible to outside users on the Internet, so it is much more difficult for a hacker to target a

machine on your network. Second, it can block and redirect certain ports to limit the services that

outside users can access. To ensure that games and other Internet applications run properly, you

can open specific ports for outside users to access internal services on your network.

The Integrated DHCP (Dynamic Host Control Protocol) client and server services allow multiple

users to get IP addresses automatically when the router boots up. Simply set local machines as

a DHCP client to accept a dynamically assigned IP address from the DHCP server and reboot.

Each time a local machine is powered up; the router recognizes it and assigns an IP address to

instantly connect it to the LAN.

For advanced users, Virtual Service (port mapping) functions allow the product to provide limited

visibility to local machines with specific services for outside users. For instance, a dedicated web

server can be connected to the Internet via the router and then incoming requests for web pages

that are received by the router can be rerouted to your dedicated local web server, even though

the server now has a different IP address.

Virtual Server can also be used to re-task services to multiple servers. For instance, you can set the

router 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.
