BiPAC 7402R2 ADSL2+ VPN Firewall Router

Chapter 4: Configuration

You can find six items under the Firewall section: General Settings, Packet Filter, Intrusion Detection,

URL Filter and Firewall Log.

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 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 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.

Any remote user who is attempting to perform this action may result in blocking

all the accesses to configure and manage of the device from the Internet.
