Chapter 1: Introduction
Introduction to your Router
Thank you for purchasing BiPAC 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 BiPAC 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 BiPAC 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 BiPAC 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 BiPAC 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.
