A proxy is a server that acts as an intermediary between a protected Local Area Network (firewall) and the Internet. Some home networks, corporate intranets, and Internet Service Providers (ISPs) use proxy servers. The proxy server ensures that all data transmission between the Internet and a user on the LAN is authorized.
If you are behind a firewall, you can use the advanced preferences to customize your access. You can choose from the following:
Before you configure a proxy server, obtain the host name and port number of your proxy server. If you do not know the host name or port number of your proxy server, ask your firewall administrator.
Click the Advanced button.
The Advanced Settings dialog box appears.
Enter your proxy Server Address.
The proxy server address can be the server's name or IP address.
Enter the Port number.
Typically, this number is 8080.
