Will the BroadGuard function in a Macintosh environment?
Yes, but the BroadGuard’s setup pages are accessible only through Internet
Explorer v4.0 or Netscape Navigator v4.0 or higher for Macintosh.
With which type of firewall is the BroadGuard equipped?
The BroadGuard uses NAT, anti-DoS (Denial of Service) and (SPI) Stateful
Packet Inspection.
What is DoS (Denial of Service)?
The goal of a Denial of Service (DoS) attack is not to steal information, but to
disable a device or network so users no longer have access to network
resources. For example, "TearDrop", a DoS hacker tool which is widely
available on the Internet, allows users to remotely crash any unprotected
Windows computer on the Internet. Most types of Internet attacks try to
exploit the weaknesses in the TCP stacks of the operating systems of host
machines. BroadGuard protects against the following types of DoS attacks:
SYN Flooding
Ping of Death
LAND attacks
Smurf attacks
IP Spoofing
TearDrop
WinNuke
