The ZyAIR wireless gateways employ a stateful inspection firewall with DoS (Denial of Service) 
protection. By default, when the firewall is activated, all incoming traffic from the WAN to the LAN is 
blocked unless it is initiated from the LAN. The ZyAIR firewall supports TCP/UDP inspection, DoS 
detection and prevention, real time alerts, reports and logs.

      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.
