4-1 Firewall
The Firewall setting page allows you to configure advanced Firewall functions to provide
superior security for your network environment. You must click “Apply” to make any changes
active.
■ Firewall Option Enable this function to prevent DoS (Denial of Service) attacks and to use
SPI (Stateful Packet Inspection). SPI function will check the contents of incoming data
packets for malicious attacks.
■ Web Filter This feature provides the ability to filter potential risks contained in web pages
accessed by LAN users.
Web proxy is a server your device will connect to when you access any web site. Setting
a web proxy can save accessing time but may create a security issue by bypassing any
URL filters or IP blocking you have configured. For example, if you configure the
Broadband Firewall Router to block the access of 216.115.102.76 that is the IP address
of www.yahoo.com, it will fail because your computer will connect to web proxy server
instead to connect to Yahoo’s IP address if you set web proxy.
Java & Active X are programming languages for web pages. However, some Trojan
programs are also written in these programming languages. If you deny either of these,
you may not be able access some parts of web sites.
