4.3.4 Firewall

Firewall and Access Control

Your router includes a full SPI (Stateful Packet Inspection) firewall for controlling Internet

access from your LAN, as well as helping to prevent attacks from hackers. In addition to this,

when using NAT (Network Address Translation) the router acts as a “natural” Internet

firewall, since all PCs on your LAN use private IP addresses that cannot be directly

accessed from the Internet. See the

WAN

configuration section for more details on NAT.

Firewall

: Prevents access from outside your network. The router provides three levels of

security support:

NAT natural firewall

: This masks LAN users’ IP addresses, which are invisible to outside

users on the Internet, making it much more difficult for a hacker to target a machine on your

network. This natural firewall is on when the NAT function is enabled.

When using Virtual Servers (port forwarding) your PCs are exposed to the

degree specified in your Virtual Server settings provided the ports specified

are opened in your firewall packet filter settings.

4.3.4.1 Packet Filter

Packet filtering enables you to configure your router to block specified internal/external

users (

IP address

) from Internet access, or you can disable specific service requests (

Port

number

) to /from Internet. This configuration program allows you to set up to 6 different filter

rules for different users based on their IP addresses or their network Port number. The

relationship among all filters is

“or”

operation, which means that the router checks these

different filter rules one by one, starting from the first rule. As long as one of the rules is

satisfied, the specified action is taken.
