BIPAC-74x Series Router – 741 GE, 741 GE V2.0 and 743 GE 
 
Chapter 1: Introduction 
A 4-port 10/100Mbps fast Ethernet switch is built in with automatic switching between MDI 
and MDI-X for 10Base-T and 100Base-TX ports. An Ethernet straight or cross-over cable 
can be used directly for auto detection. 
 Multi-Protocol to Establish A Connection 
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 the ISP. The 
product also supports VC-based and LLC-based multiplexing. 
 Quick Installation Wizard 
Supports a WEB GUI page to install this device quickly. With this wizard, end users can 
enter the information easily which they get from their ISP, then surf the Internet 
immediately. 
 Universal Plug and Play (UPnP) and UPnP NAT Traversal 
This protocol is used to enable simple and robust connectivity among stand-alone devices 
and PCs from many different vendors. It makes network simple and affordable for users. 
UPnP architecture leverages TCP/IP and the Web to enable seamless proximity 
networking in addition to control and data transfer among networked devices. With this 
feature enabled, users can now connect to Netmeeting or MSN Messenger seamlessly. 
 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 SOHO firewall with NAT technology, automatically detects and blocks Denial of 
Service (DoS) attacks. URL blocking, packet filtering and SPI (Stateful Packet Inspection) 
are also supported. The hacker’s attack will be recorded associated with timestamp in the 
security logging area. More firewall functions will always be implemented through updated 
firmware releases. 
 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/. More 
than 5 DDNS servers are supported. 
 Virtual Private Network (VPN) 
Allows user to make a tunnel with a remote site directly to secure the data transmission 
among the connection. User can use embedded PPTP client/server, IKE and IPSec which 
are supported by this router to make a VPN connection or users can run the PPTP client in 
PC and the router already provides IPSec and PPTP pass through function to establish a 
VPN connection if the user likes to run the PPTP client in his local computer.
