Network Proxy settings

A proxy server regulates access to the Internet, and prevents external computers from accessing your network. If you are on a network that uses a proxy server to connect to the Internet, you can provide proxy server details to Norton Internet Security. You can use the Network Proxy Settings window to specify the automatic configuration URL, the proxy settings, and the authentication details. Norton Internet Security uses the proxy settings and authentication details to connect to the Internet automatically, whenever required. For example, LiveUpdate uses the specified proxy server settings to retrieve updates. You must ensure that you specify the proxy server details for LiveUpdate to run successfully.

In some cases, your network uses an automatic configuration URL or script for managing Internet access. In this case, you must provide the URL of the required PAC (Proxy Automatic Configuration) file. A PAC file contains the code that lets your browser know about the proxy settings for different Web sites over the Internet. It also contains the words which you want to filter and block while you access the Internet. You can also choose the option that lets your browser to automatically detect the proxy settings.

If you want your manual settings in the network, ensure that you disable the Automatic Configuration options.
