<h1 class="topictitle1">Scenario: Connect your office LAN to the Internet with a modem</h1>
|
||
|
|
<div><p>Administrators typically set up office networks that allow employees
|
||
|
|
access to the Internet. They can use a modem to connect the iSeries™ server
|
||
|
|
to an ISP. LAN-attached PC clients can communicate with the Internet using
|
||
|
|
the iSeries server
|
||
|
|
as a gateway.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Situation</h4><p>The corporate application that your company
|
||
|
|
uses now requires your users to access the Internet. Since the application
|
||
|
|
does not require large amounts of data exchange, you need to be able to use
|
||
|
|
a modem to connect both your iSeries server and LAN-attached PC clients to the
|
||
|
|
Internet. The following illustration describes an example of this situation.</p>
|
||
|
|
</div>
|
||

|
<div class="section"><div class="fignone"><span class="figcap">Figure 1. Connect your office LAN to the Internet with a modem</span><br /><img src="rzaiy506.gif" alt="Connect your office LAN to the Internet with a modem" /><br /></div>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Solution</h4><p>You can use your integrated (or other compatible)
|
||
|
|
modem to connect your iSeries to your ISP. You need to create a PPP originator
|
||
|
|
profile on the server to establish the PPP connection to the ISP.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>After you make the connection between the iSeries and the ISP, your LAN-attached
|
||
|
|
PCs can communicate with the Internet using the iSeries as a gateway. In the originator
|
||
|
|
profile, you will want to make sure that Hide addresses option is on, so that
|
||
|
|
the LAN clients, which have private IP addresses, can communicate with the
|
||
|
|
Internet.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>Now that your iSeries and network is attached to the Internet,
|
||
|
|
you must understand your security risk. Work with your ISP to understand their
|
||
|
|
security policy and take further actions to protect your server and network.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>Depending on your Internet usage, bandwidth might become a concern.
