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.
