Applications and features
In this chapter, we present the most common applications and features
of MW1122. The use and configuration of your Nokia MW1122 may
be different from the configurations presented in this manual, even for
similar applications. The configurations presented in this manual
represent a typical way of using MW1122 for the corresponding
applications.
2.1 Applications
The three typical applications discussed below are the Internet access,
remote work, and office LAN interconnection.
Internet access
Your access to the Internet is provided by your Internet Service
Provider (ISP). Nokia MW1122 connects you through your telephone
line and the ATM (Asynchronous Transfer Mode) network to the
network of your ISP, which, in turn, is connected to the Internet.
Hence, all your data goes through the ISP’s network. If you are using
only one ISP for your Internet access, your ISP may give you a limited
set of IP addresses belonging to its address space that you may utilise
in your desktop and laptop computers on your home network.
However, in many cases it is more practical to separate your own
private LAN from the ISP’s public network by using private IP
addresses. This way you are not limited to the number of public IP
addresses provided by your ISP but you can manage your own address
space independently. For this you will need to use NAPT (Network
Address Port Translation) feature available in your MW1122 modem.
