Firewall 

26-1 

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.  

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.  

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. 

 

 

 

 

 

 

 

 

 

 

 

Use the web configurator or the command interpreter to configure the firewall rules.

 

 
                          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.
