Use a Netopia Firewall
BreakWater Basic Firewall. BreakWater delivers an easily selectable set of pre-
configured firewall protection levels. For simple implementation these settings (comprised
of three levels) are readily available through Netopia’s embedded web server interface.
BreakWater Basic Firewall’s three settings are:
• ClearSailing
ClearSailing, BreakWater's default setting, supports both inbound and outbound traffic.
It is the only basic firewall setting that fully interoperates with all other Netopia software
features.
• SilentRunning
Using this level of firewall protection allows transmission of outbound traffic on pre-con-
figured TCP/UDP ports. It disables any attempt for inbound traffic to identify the Gate-
way. This is the Internet equivalent of having an unlisted number.
• LANdLocked
The third option available turns off all inbound and outbound traffic, isolating the LAN
and disabling all WAN traffic.
☛ NOTE:
BreakWater Basic Firewall operates independent of the NAT functionality on
the Gateway.
