The LAN-Safe Firewall is a good choice to protect
Modem
LAN-Safe Firewall
(MC170A)
OVERVIEW
The Internet is based on UNIX
®
systems which were
originally designed for open and easy connectivity. But that
same open architecture can make it easy for hackers to break
into your LAN via the Internet.
The LAN-Safe Firewall prevents unauthorized LAN access
from your Internet connection by disconnecting the LAN
connection while the modem is in use. There is never a
direct connection between the Internet and your LAN.
The LAN-Safe Firewall is an external hardware security
device designed for PCs or servers that have both 10BASE-T
Ethernet network interface cards and modems.
When you dial out to the Internet, the LAN-Safe Firewall
automatically disconnects the LAN. When you're done with
the modem, the unit automatically reconnects the LAN.
Although the LAN-Safe Firewall can be used at various
points on the LAN, it's primarily used in smaller LAN environ-
ments without conventional firewalls and where one or more
users access the Internet while their PC is connected to the
LAN.
With the LAN-Safe Firewall installed, the LAN connection
is physically broken while the modem session is in progress —
and your network is effectively safeguarded from LAN
damage or security breaches from Internet connections. Once
the modem call is completed, the unit automatically restores
the link to the LAN.
The LAN-Safe Firewall can also be used in other install-
ations, even those with conventional firewalls that restrict
access to high-priority servers while dialup modems are in use.
It doesn't matter if the server supports the modem connection
or if it's an adjacent server— the LAN-Safe Firewall provides

a small to mid-sized 10BASE-T LAN.
PC
10BASE-T network
the extra protection your network needs wherever there's a
modem connection.
Installation is easy— no training or maintenance is
required. Plus the LAN-Safe Firewall is powered from
the telco line, so it can be used practically anywhere.
The LAN-Safe Firewall is a simple but highly effective
network solution that keeps hackers out.
Choose either the basic LAN-Safe Firewall (MC170A
for standalone or MC171A for wallplate) or the enhanced
model (MC172A).
The MC172A, when operating in the enhanced mode,
gives you all the protections of the basic disconnect, but
its LAN connection isn't automatically restored when your
modem call is completed. In fact, it doesn't restore the link
until it runs a program like a virus scan. That way, you can
prevent downloaded viruses from infecting your entire
network. Or you can run an analysis or audit program of
your choice, which you set up through an encrypted,
password-protected program included with the MC172A.
You can operate the switch-selectable device as a basic
or enhanced LAN-Safe Firewall. When used as a basic unit,
it allows multiple units to be stacked together to accomm-
odate operation with multiple modems or servers.
The wallplate versions feature punchdown 110 connectors;
these are compatible with the EIA/TIA 568B wiring standard
for easy replacement.
A typical application might be an office with a small
10BASE-T LAN connected to the LAN-Safe Firewall on one
computer that's used for Internet access.
