Enabling the Firewall

This chapter shows you how to get started with the HomeSafe firewall.

26.1 Remote Management and the Firewall

When SMT menu 24.11 is configured to allow management (see the Remote Management chapter) and the firewall is enabled:

•The firewall blocks remote management from the WAN unless you configure a firewall rule to allow it.

•The firewall allows remote management from the LAN.

26.2 Access Methods

The web configurator is, by far, the most comprehensive firewall configuration tool your HomeSafe has to offer. For this reason, it is recommended that you configure your firewall using the web configurator, see the following chapters for instructions. SMT screens allow you to activate the firewall and view firewall logs.

26.3 Enabling the Firewall

From the main menu enter 21 to go to Menu 21 - Filter and Firewall Setup to display the screen shown next.

Enter option 2 in this menu to bring up the following screen. Press [SPACE BAR] and then [ENTER] to select Yes in the Active field to activate the firewall. The firewall must be active to protect against Denial of Service (DoS) attacks. Additional rules may be configured using the web configurator.

Menu 21.2 - Firewall Setup

The firewall protects against Denial of Service (DoS) attacks when it is active.

Your network is vulnerable to attacks when the firewall is turned off.

Refer to the User's Guide for details about the firewall default policies.

You may define additional Policy rules or modify existing ones but please exercise extreme caution in doing so.

Active: No

You can use the Web Configurator to configure the firewall.

Press ENTER to Confirm or ESC to Cancel:
