<h3 id="scenario8">Scenario: Configure a multi-hop connection through a remote server</h3>
|
|
<p class="sectionscenariobar"><span class="bold">Situation</span></p>
|
|
<p>Suppose you are responsible for maintaining an iSeries™ server for
|
|
MyCompany, a medium-sized 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. MyCompany has an iSeries server on
|
|
a private network that accesses the Internet through a VPN multi-hop gateway.
|
|
The multi-hop gateway could be either an iSeries or a router that supports L2TP multi-hop
|
|
(chained tunnels). In this case, you create a connection from your iSeries server through
|
|
a multi-hop connection. Because you do not need to provide connections for
|
|
other systems, you do not need to consider providing connections for other
|
|
servers or partitions.</p>
|
|
<a name="wq129"></a>
|
|
<div class="notetitle" id="wq129">Note:</div>
|
|
<div class="notebody">The HMC cannot currently provide this
|
|
multi-hop gateway support.</div>
|
|
<p class="sectionscenariobar"><span class="bold">Solution</span></p>
|
|
<p>Create a Universal Connection to IBM® through the multi-hop connection. In this
|
|
case, you establish a connection between two virtual private network tunnels
|
|
from a remote server to electronic customer support.</p>
|
|
<p></p>
|
|
<p class="sectionscenariobar"><span class="bold">Advantages</span></p>
|
|
<p>This scenario provides the following advantages:</p>
|
|
<ul>
|
|
<li>MyCompany can create a connection from its iSeries system on a private network through
|
|
another iSeries or router that has direct connectivity to the Internet.</li>
|
|
<li>The multi-hop connection provides a 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>A multi-hop connection provides a high degree of security between your iSeries system and electronic customer support by shielding it from the Internet.</li>
|
|
<li>High speed access to electronic customer support is available with this
|
|
option.</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 the network though a multi-hop connection over the
|
|
Internet. The objectives of this scenario are as follows:</p>
|
|
<ul>
|
|
<li>To create a secure multi-hop connection between MyCompany and electronic
|
|
customer support over 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 VPN multi-hop gateway.</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>An L2TP tunnel is established to the VPN multi-hop gateway.</li>
|
|
<li>Seeing that the connection request is for IBM service, a VPN is established through
|
|
your existing Internet connection to a VPN Gateway at IBM.</li>
|
|
<li>The L2TP tunnel is chained to the VPN connection.</li>
|
|
<li>The service application communicates with the appropriate IBM servers to perform
|
|
the requested service.</li></ul>
|
|
<a name="scenprereqs8"></a>
|
|
<p id="scenprereqs8" class="sectionscenariobar"><span class="bold">Prerequisites
|
|
and assumptions</span></p>
|
|
<p>The prerequisites for enabling electronic customer support over a remote
|
|
multi-hop connection include:</p>
|
|
<ul>
|
|
<li>The iSeries server must have IP connectivity to the VPN multi-hop gateway.</li>
|
|
<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 that the VPN multi-hop gateway has been configured to allow connections
|
|
to IBM. If you are using an iSeries as the VPN multi-hop gateway, see <a href="scenario5.htm#scenario5">Configure a direct Internet connection from a server that
|
|
provides connectivity for other systems or partitions</a>. Other options are
|
|
discussed in <a href="detvpnaddy.htm#detvpnaddy">Determine the IBM VPN Gateway addresses</a>.</li></ul>
|
|
<p class="sectionscenariobar"><span class="bold">Current® System or Partition configuration
