8.6Firewall Content Filter Screen

The Content Filter screen allows users to restrict Web features, add keywords for blocking, and designate a trusted computer. A content filtering profile conveniently stores your custom settings for the following features.

Restrict Web Features

The FSG1100HN can disable Web proxies and block Web features such as ActiveX controls, Java applets, and cookies.

Keyword Blocking URL Checking

The FSG1100HN checks the URL’s domain name (or IP address) and file path separately when performing keyword blocking.

The URL’s domain name or IP address is the characters that come before the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the domain name is www.zyxel.com.tw.

The file path is the characters that come after the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the file path

is news/pressroom.php.

Since the FSG1100HN checks the URL’s domain name (or IP address) and file path separately, it will not find items that go across the two. For example, with the

URL www.zyxel.com.tw/news/pressroom.php, the FSG1100HN would find “tw” in the domain name (www.zyxel.com.tw). It would also find “news” in the file path (news/pressroom.php) but it would not find “tw/news”.

The FSG1100HN can block Web sites with URLs that contain certain keywords in the domain name or IP address. For example, if the keyword "bad" was enabled, all sites containing this keyword in the domain name or IP address will be blocked, e.g., URL http:// www.website.com/bad.html would be blocked. Select Enable to enable this feature.
