General Settings

You can choose not to enable the Firewall and still have access to URL Filter and IM/P2P Blocking, or you can
enable the Firewall using 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 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 predefined 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. For more detailed on level of
preset port filter information, refer to Table 1: Predefined Port Filter.
If you choose of the preset security levels and add custom filters, this level of filter rules will be saved even and do
not need to re-configure the rules again if you disable or switch to other firewall level.
The "Block WAN Request" is a stand-alone function and not related to whether security is enabled or disabled.
Mostly this is used to preventing a hacker on the WAN from using any scan tools.
