<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™ 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® 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>

|
|
<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® 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™ 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–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® 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>
