Configuration Examples Useful Information on Internet Access 8.6 Useful Information on Internet Access 8.6.1 Costs The OpenCom 100 uses a router function to access the Internet, which means that it automatically establishes an Internet connection when required and terminates the connection after a certain period of time if no data are being transmitted. Unfortunately, programmes other than those typically intended to access the Internet (such as your browser or your e-mail software) may send out data packets which cause an Internet connection to be established, even if these programmes are not strictly Internet-associated applications. Examples of such programmes are the MicrosoftTM XPTM operating system, various multimedia programmes such as RealplayerTM and anti-virus applications that may establish an Internet connection for automatic updates (the so-called "phone home function"). It is therefore highly advisable to limit ISP access by specifying the maximum monthly connection time under Connection time per month in the Network: WAN: [Provider] menu on the web console. 8.6.2 Using the Web A Web browser not only enables you to use the OpenCom 100 Configurator from every workstation computer but also to obtain a wealth of information from the Internet. Simply enter the desired URL in the address field of the browser. Access from a stand-alone PC via an online service differs from Internet access via the OpenCom 100 in the following respects: ■ When you request a Web page, dialling in results automatically. There is no display of dialogues with manual confirmation of dialling in or hanging up. ■ Requesting Web pages is not a connection-orientated service. When the Web page has been loaded completely, the TCP/IP connection is cleared. If you do not request further Web pages, the OpenCom 100 automatically releases the connection to the Internet after a certain, specifiable duration. ■ It is possible to call up Web pages simultaneously from several workstations. ■ The OpenCom 100 can block access to certain Web pages by means of filter lists. 99
