Section 3 General
BreakWater Basic Firewall
BreakWater delivers an easily selectable set of pre-configured firewall pro-
tection levels. These settings are readily available for simple implementa-
tion through Cayman’s embedded web server interface.
BreakWater provides you and your network with:
• Protection for all LAN users.
• Elimination of firewall management software on individual PC’s.
• Immediate protection through three pre-configured firewall levels.
• Elimination of the complexity associated with developing firewall rules.
BreakWater Settings
BreakWater Basic Firewall’s three settings are:
ClearSailing
ClearSailing provides protection against network initiated inbound traffic,
while securely passing outbound traffic through the Gateway. In conjunc-
tion with Network Address Translation, this setting allows authorized
remote diagnostic support while protecting against undesired inbound
traffic.
SilentRunning
Using this level of firewall protection allows secure transmission of out-
bound traffic, but disables any attempt for inbound traffic to identify the
Gateway. This is the Internet equivalent of having an unlisted number.
LANdLocked
The third option available turns off all inbound and outbound traffic, isolat-
ing the LAN and disabling all WAN traffic.
See page 69 for How To Configure BreakWater instructions includ-
ing a table of user tips.
BreakWater Basic Firewall operates independent of the Gateway’s NAT
functionality.
