When using Virtual Server, your PC will become exposed to a certain degree

to unknown users if specific ports are opened in the firewall packet filter

setting. The degree of exposure depends on the parameter set in the Virtual

Server setting.

Firewall and Access Control

Your router includes a full SPI (Stateful Packet Inspection) firewall to control Internet access on your network. This

feature also protects your system from being attacked by hackers. When using NAT, the router acts as a “natural”

Internet firewall, as all PCs on your LAN will have their own private IP address which is not directly accessible from the

Internet. The router provides three levels of security support.

NAT natural firewall:

This masks LAN users’ IP addresses which are invisible to users on the Internet, thus making it

more difficult for a hacker to target a machine on your network. This natural firewall is turned on when the NAT function

is enabled.

Firewall Security and Policy (General Settings):

Inbound direction of Packet Filter rules to prevent unauthorized

computers or applications from accessing your local network from the Internet.

Intrusion Detection:

Enable Intrusion Detection to detect, prevent and log malicious attacks.

Access Control:

Prevent access from computers on your local network:

Firewall Security and Policy (General Settings):

Outbound direction of Packet Filter rules to prevent unauthorized

computers or applications from accessing the Internet.

URL Filter:

To block computers on your local network from unwanted websites.

The items under the Firewall section are: General Settings, Packet Filter, Intrusion Detection, URL Filter, IM/P2P Blocking

and Firewall Log.

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.

Packet Filter

This function is only available when Firewall is enabled with one of the four security levels selected (All blocked, High,

Medium and Low). The preset port filter rules in the Packet Filter must be modified accordingly to the security

level selected. See Table1: Predefined Port Filter for more detailed information.
