General Settings 

You can choose not to enable Firewall, to add all filter rules by yourself, or enable the 
Firewall using preset filter rules and modify the port filter rules as required. The Packet 
Filter is divided into two sections: Port Filters and Address Filters, used to filter packets 
based-on Applications (Port) or IP addresses. 

There are four options when you enable the Firewall, they are: 

 All 

blocked/User-defined: 

no pre-defined port or address filter rules by default, 

meaning that all inbound (Internet to LAN) and outbound (LAN to Internet) packets 
will be blocked. Users have to add their own filter rules for further access to the 
Internet. 

   High/Medium/Low security level: the pre-defined port filter rules for High, Medium 

and Low security are displayed in Port Filters of Packet Filter.  

Select either High, Medium or Low  security level to enable the Firewall. The only 
difference between these three security levels is the preset port filter rules in the Packet 
Filter. Firewall functionality is the same for all levels; it is only the list of preset port filters 
that changes between each setting. 

If you choose of the preset security levels and then add custom filters, you may 
temporarily disable the firewall and recover your custom filter settings by re-selecting the 
same security level. 

The “Block WAN Request” is a stand-alone function and not relate to whether security 
enable or disable. Mostly it is for preventing any scan tools from WAN site by hacker.
