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.
When the Firewall is enabled, you can also enable the Firewall Logging function. The
Firewall Logs can be viewed via the Status – Event Log section of the web interface.
Please see the Status section of this manual for more information. If you encounter any
access problems with the Firewall enabled, you can check this log to identify whether the
problem is caused by the Packet Filter rules or not. Any time a connection attempt is
blocked by the firewall a corresponding entry will appear in the Event Log to assist in
troubleshooting and firewall port filter configuration.
