The firewall controls the allowance and denial of packets through the router.
The
Firewall Setup in the Vigor2960 Series mainly consists of packet filtering, Denial of
Service (DoS) and URL (Universal Resource Locator) content filtering facilities. These
firewall filters help to protect your local network against attack from outsiders. A firewall
also provides a way of restricting users on the local network from accessing inappropriate
Internet content and can filter out specific packets, which may trigger unexpected outgoing
connection such as a Trojan.
The following sections will explain how to configure the Firewall . Users can select IP Filter ,
DoS Defense, MAC Block and Port Block options from Firewall menu. The DoS Defense
facility can detect and mitigate the DoS attacks.
