9.2 Access Rule 
Users may turn on/off the setting to permit or forbid any packet to access internet. Users may 
select to set different network access rules: from internal to external or from external to internal. 
Users may set different packets for IP address and communication port numbers to filter Internet 
access rules. 
Network  access  rule  follows  IP  address,  destination  IP  address,  and  IP  communications 
protocol  status  to  manage  the  network  packet  traffic  and  make sure whether their access  is 
allowed by the firewall. 
9.2.1 Default Rule 
The device has a  user-friendly network access regulatory tool.  Users may define network 
access rules. They can select to enable/ disable the network so as to protect all internet access. 
The following describes the internet access rules: 
  All traffic from the LAN to the WAN is allowed - by default.   
  All traffic from the WAN to the LAN is denied - by default.   
  All traffic from the LAN to the DMZ is allowed - by default.   
  All traffic from the DMZ to the LAN is denied - by default.   
  All traffic from the WAN to the DMZ is allowed - by default. 
  All traffic from the DMZ to the WAN is allowed - by default.   
Users may define access rules and do more than the default rules. However, the following 
four extra service items are always on and are not affected by other user-defined settings.   
* HTTP Service (from LAN to Device) is on by default (for management)   
*  DHCP  Service  (from  LAN  to  Device)  is  set  to  on  by  default  (for  the  automatic  IP
