Introduction
The OfficeConnect Internet Firewall acts as a secure barrier
to protect a private LAN from hacker attacks from the
Internet. It can also be used to control the access that LAN
users have to the Internet.
The OfficeConnect Internet Firewall 25 supports up to 25
users on the LAN.
The OfficeConnect Internet Firewall DMZ supports up to
100 users on the LAN. In addition, the OfficeConnect
Internet Firewall DMZ has a
Demilitarized Zone
(DMZ) port.
Servers and workstations attached to this port are publicly
accessible from the Internet, but remain secure from
Denial-of-Service
(
DoS
) hacker attacks from the Internet. If
an Internet Firewall feature described in this guide applies
only to the DMZ version, a note tells you this.
The OfficeConnect Web Site Filter is an optional extra that
can be used with either variant of the Internet Firewall. You
can use it to prevent LAN users accessing Web sites that fit
into categories that are considered inappropriate for
business use. The Web Site Filter updates the Internet
Firewall automatically with the latest URLs matching
selected categories. It is available as a 12-month
