Any remote user attempting to perform this action may cause all access to the router
to be blocked, which will result in no configuration or managing of the device from
the internet.
General Settings
You can choose to disable Firewall and still be able to access the URL Filter 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 come from hackers.
