Chapter 1 - IntroductionWelcome to the world of broadband connectivity to the Internet.
The Multi-Tech Broadband RouteFinder connects a cable modem or DSL modem to an
Ethernet LAN to provide high-speed broadband access to the Internet for up to 253 users.
The Broadband Router features a built-in 4-port 10/100M bps switch, one asynchronous
port for backup Internet access or dial-in remote access, firewall services, and network
security. This product is ideal for any busi ness looking for cost-effective broadband access
to the Internet for every user on th e LAN or for the home user looking to share their DSL
cable connection.
Connects up to 253 internal IP addresses to the Internet with broadband speed.
With the RouteFinder, up to 253 users are connected to the Internet with only one IP
account. The WAN Ethernet port has a bandwidth of 10M bps which is 179 times faster
than a 56K modem and can support DSL or cable speeds of up to 4M bps.
Built-in 10/100 Switch. The integrated 4-port 10/100 switch eliminates the need for an
additional hub or switch to connect users n ot on a LAN. It ensures high-speed transmission
and can serve as a completely dedicated full duplex backbone.
Network Security. The RouteFinder uses the NAT protocol to provide security from
hackers attempting to access the office LAN without the extra cost of a firewall. It
implements firewall and gateway security for LAN-based resources. Additionally, the
RouteFinder supports Internet access r estriction by IP address, client protocols or port
number.
Dial Backup or Dial-in RAS Port. The RouteFinder also provides an additional
asynchronous port that, when connected to a dial-up modem or ISDN terminal adapter,
can serve as a backup resource for Intern et access if your cable or DSL service goes down.
It can also serve as dial-in remote access for y our telecommuters or mobile users.
Virtual Server Support. In addition to providing shared Internet access, the RouteFinder
can support Web, FTP or other Internet servers. Once configured, the RouteFinder accepts
only unsolicited IP packets addressed to the Web, FTP, or other specified servers.
LAN Segmentation. For added LAN security, the RouteFinder can be used to segment
the LAN by connecting the corporate servers to one RouteFinder Ethernet port and the
Internet servers to the other Ethe rnet port. This configuration puts the corporate servers
behind a firewall and the Internet servers outside the firewall. To continue to provide
Internet access, connect a modem or ISDN terminal adapter to the RouteFinder’s
asynchronous port.
