INTRODUCTION
The BroadBand IP Gateway + Fast EtherSwitch is an integrated Internet IP sharing device
with a built-in 4-port 10/100Mbps N-Way Fast Ethernet switch. It is the perfect solution to
connect a small group of PCs to a high-speed broadband Internet connection. Multiple users
can have high-speed Internet access simultaneously via one single IP address (Internet
account) of the Cable/xDSL modem.
This product also serves as an Internet firewall, protecting your network from being accessed
by outside users. All incoming data packets are monitored and filtered. It can also be
configured to block internal users from accessing to the Internet.
This device provides an easy-to-setup GUI program for Windows 95/98/ME/NT/2000.
Thanks to both DHCP client and DSCP server, which complete the network configuration
automatically. The built-in 4-port Fast Ethernet Switch lets users plug the network cable into
the device without buying additional Hub/Switch. With the functions of the IP Share, you can
enjoy the true Plug & Play installation.
In addition, the unit is equipped with an Incoming Mail Indicator, which will lit green when
there is e-mail waiting to be retrieve at the mail server.
