<h3 id="scenario5">Scenario: Configure a direct Internet connection from a
server that provides connectivity for other systems or partitions</h3>
<p class="sectionscenariobar"><span class="bold">Situation</span></p>
<p>Suppose you are responsible for maintaining an iSeries&trade; server for
MyCompany, a small manufacturing company in Boone, Iowa. As part of providing
this support, you need to establish a connection between electronic customer
support and MyCompany's iSeries server. Since MyCompany has an Internet
network connection and a fixed global routable IP address cable modem, you
can create a connection from your iSeries server through your cable modem. With
this system, your server provides connectivity (as a VPN multi-hop gateway
and a Service and Support proxy) for the three other MyCompany servers that
need to connect to electronic customer support services.</p>
<p class="sectionscenariobar"><span class="bold">Solution</span></p>
<p>Create a Universal Connection to IBM&reg; through a direct Internet connection.
The Universal Connection wizard creates all the required definitions for the
connection to electronic customer support. To provide connectivity for other
systems, the wizard will create an L2TP terminator profile, or you can select
an existing L2TP terminator profile. See <a href="../rzaiy/rzaiyvrtline.htm">L2TP (virtual
line)</a> for additional information about L2TP terminator profiles. In addition,
the wizard will configure the Service and Support proxy.</p>
<p class="sectionscenariobar"><span class="bold">Advantages</span></p>
<p>This scenario provides the following advantages: </p>
<ul>
<li>MyCompany can use its existing hardware and Internet provider
to receive benefit from electronic customer support. You can configure this
connection through the Universal Connection wizard or CL commands.</li>
<li>The Internet connection provides a simple means of ensuring that MyCompany
has electronic customer support available for ease of troubleshooting server
problems, tracking current system hardware and software, or receiving software
updates and fixes.</li>
<li>MyCompany's other three servers can remotely connect to electronic customer
support through a single server. MyCompany would only need connectivity from
one system.</li>
<li>A direct Internet connection provides a high-speed connection to electronic
services.</li>
<li>With this scenario the other MyCompany servers are protected from the
Internet.</li></ul>
<p class="sectionscenariobar"><span class="bold">Objectives </span></p>
<p>In this scenario, the customer wants to ensure that IBM can support
the MyCompany system over a direct connection to the Internet. The objectives
of this scenario are as follows: </p>
<ul>
<li>To create a direct connection between the MyCompany's four servers and
electronic customer support through the Internet.</li>
<li>To automate customer support through electronic customer support and services</li>
<li>To allow electronic customer support to create an electronic hardware
and software inventory of MyCompany's iSeries system</li>
<li>To permit electronic customer support to send software fixes and updates
to MyCompany over the network</li></ul>
<p class="sectionscenariobar"><span class="bold">Details</span></p>
<p>The following diagram illustrates connecting the MyCompany iSeries server to
electronic customer support through a direct connection to the Internet.</p>
<div class="mmobj">
<img src="rzatj509.gif" alt="Diagram that depicts a direct Internet connection from a server that provides connectivity for other systems or partitions" /></div>
<p><span class="bold">Configuring Universal Connection</span></p>
<ul>
<li>iSeries Navigator launches the Universal Connection Wizard to configure
the connection. This only needs to be done once unless some configuration
information needs to be updated.</li></ul>
<p><span class="bold">Using Universal Connection</span></p>
<p>When a Service Application wants to use the Universal Connection to communicate
with IBM the following will occur:</p>
<ul>
<li><span class="bold">If the service application is not providing
its own security and iSeries A is connecting:</span> A Virtual Private Network
(VPN) is established through your existing Internet connection to a VPN Gateway
at IBM.</li>
<li><span class="bold">If the service application is not providing
its own security and iSeries B, C, or D are connecting:</span> An L2TP tunnel
is established to iSeries A which initiates a VPN through your existing Internet
connection to a VPN Gateway at IBM.</li>
<li><span class="bold">If the service application is providing
its own security and iSeries A is connecting:</span> An HTTP or HTTPS connection
is made with the appropriate IBM servers.</li>
<li><span class="bold">If the service application is providing
its own security and iSeries B, C, or D are connecting and they support a proxy:</span> An HTTP or HTTPS connection is made through the Service and Support
proxy server.</li></ul>
<p>The service application communicates with the appropriate IBM servers to perform
the requested service.</p>
<a name="scenprereqs5"></a>
<p id="scenprereqs5" class="sectionscenariobar"><span class="bold">Prerequisites
and assumptions</span></p>
<p>The prerequisites for enabling electronic customer support over a direct
Internet connection include:</p>
<ul>
<li>The iSeries server must have a globally routable IP address, or the server
must be behind a NAT firewall with a globally routable address.</li></ul>
<ul>
<li>Ensure that the iSeries Access for Windows&reg; and iSeries Navigator exist on your personal computer,
as described in the <a href="../rzaij/rzaijrzaijinstall.htm">iSeries Access for Windows:
Installation and setup</a> topic.</li>
<li>Ensure that you install all of the latest service packs for iSeries Navigator.
The scenarios show using the V5R4 version of the software.</li>
<li>Ensure that TCP/IP is active. You can start TCP/IP through the Start TCP/IP
(STRTCP) command.</li>
<li>You must have security officer (*SECOFR) authority with *ALLOBJ,
*IOSYSCFG, and *SECADM special authorities in your i5/OS&trade; user profile and *USE authority to WRKCNTINF
in order to configure the connection using the Universal Connection wizard.</li>
<li>You must install the TCP/IP Connectivity Utilities (5722&ndash;TC1).</li>
<li>You must install the Digital Certificate Manager (DCM) (5722-SS1
option 34).</li>
<li>Ensure that the QRETSVRSEC system value is set to 1. You can check this
value with the Display System Value (DSPSYSVAL) command. If this value is
not set to 1, enter a Change System Value (CHGSYSVAL) command.</li>
<li>Ensure your default TCP/IP route, or a host route, directs
traffic out the appropriate TCP/IP interface to the Internet to allow the
VPN and other service connections to be established to IBM. For VPN details,
see <a href="detvpnaddy.htm#detvpnaddy">Determine the IBM VPN Gateway addresses</a> and <a href="detsdaddy.htm#detsdaddy">Determine the IBM Service Destination addresses</a>.</li>
<li>Ensure your filter rules allow Universal Connection traffic to flow to
the Internet. For details, see <a href="packetff.htm#packetff">IP Packet Filter Firewall</a>.</li></ul>
<p class="sectionscenariobar"><span class="bold">Current&reg; system configuration steps</span></p>
<p>Assuming that TCP/IP configuration already exists and works, complete the
following steps to set up the Universal Connection when your local server
acts as a connecting point for the other three servers in MyCompany:</p>
<ol type="1">
<li><a href="scenario5.htm#step1disp2">Complete the planning work sheet.</a></li>
