About 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

configuration URL or script for managing Internet
