3.4 Firewall Setup
The firewall controls the allowance and denial of packets through the router. The Firewall Setup in the Vigor 3300 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 General Setup, IP Filter, DoS and URL Filter options from Firewall menu. The DoS facility can detect and mitigate the DoS attacks. The URL Filter can block inappropriate websites for SME.
