Use a Cayman Firewall
BreakWater Basic Firewall
BreakWater delivers an easily selectable set of pre-configured firewall pro-
tection levels. For simple implementation these settings (comprised of
three levels) are readily available through Cayman’s embedded web
server interface.
BreakWater Basic Firewall’s three settings are:
ClearSailing
ClearSailing, BreakWater's default setting, supports both inbound and out-
bound traffic. It is the only basic firewall setting that fully interoperates
with all other Cayman software features.
SilentRunning
Using this level of firewall protection allows transmission of outbound traf-
fic on pre-configured TCP/UDP ports. It 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.
