Enabling the Firewall
This chapter shows you how to get started with the ZyXEL Device firewall.
24.1  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. 
24.2  Access Methods
The web configurator is, by far, the most comprehensive firewall configuration tool your 
ZyXEL Device 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. 
24.3  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.
