General Settings

You can choose to disable Firewall and still be able to access the URL Filter, Intrusion Detection

and IM/P2P Blocking or enable the Firewall using the preset filter rules and modify the port filter

rules as required. The Packet Filter is used to filter packets based on Applications (Port) or IP

addresses.

There are four policy options to choose from:

All blocked/User-defined: no predefined 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 to access the Internet.

High/Medium/Low security level: the predefined port filter rules for High, Medium and Low

security are displayed in the Port Filters of the Packet Filter.

Select either High, Medium or Low security level to enable Firewall protection. The only difference

between these three is the preset port filter rules in the Packet Filter. Firewall function is the same

for all levels; it is only the list of preset port filters that changes between each setting. For more detail

on level of preset port filter information, please refer to Table 1: Predefined Port Filter.

If you choose the preset security levels and add custom filters, the level of filter rules will be saved

and you do not need to re-configure the rules again if you disable or switch to the other security

level.

The “Block WAN Request” is a standalone function that is not affected by whether the security is

enabled or disabled. This is used to prevent any scan tools that might be from hackers.
