Use a Motorola 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 Motorola Netopia®’s embedded web ser ver inter face.
BreakWater Basic Firewall’s three settings are:
• ClearSailing
ClearSailing, BreakWater's default setting, suppor ts both inbound and outbound traffic. It is the only
basic firewall setting that fully interoperates with all other Motorola Netopia® software features.
• SilentRunning
Using this level of firewall protection allows transmission of outbound traffic on pre-configured TCP/UDP
por ts. 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, isolating the LAN and disabling all
WAN traffic.
☛
NOTE:
BreakWater Basic Firewall operates independent of the NAT functionality on the Gateway.
