Chapter 29 Enabling The Firewall; Remote Management And The Firewall; Access Methods; Enabling The Firewall - ZyXEL Communications ZyAir G-2000 PlusV2 User Manual

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

29.1 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.

29.2 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.

29.3 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.
