<h1 class="topictitle1">Scenario: Basic business to business connection</h1>
|
|
<div><p>In this scenario, your company wants to establish a VPN between
|
|
a client workstation in your manufacturing division and a client workstation
|
|
in the supply department of your business partner.</p>
|
|
<div class="section"><h4 class="sectionscenariobar">Situation</h4><p>Many
|
|
companies use frame relay or leased lines to provide secure communications
|
|
with their business partners, subsidiaries, and vendors. Unfortunately, these
|
|
solutions are often expensive and geographically limiting. VPN offers an alternative
|
|
for companies who want private, cost-effective communications.</p>
|
|
<p>Suppose
|
|
you are a major parts supplier to a manufacturer. Since it is critical that
|
|
you have the specific parts and quantities at the exact time required by the
|
|
manufacturing firm, you always need to be aware of the manufacturer's inventory
|
|
status and production schedules. Perhaps you handle this interaction manually
|
|
today, and find it time consuming, expensive and even inaccurate at times.
|
|
You want to find an easier, faster, and more effective way to communicate
|
|
with your manufacturing company. However, given the confidentiality and time-sensitive
|
|
nature of the information you exchange, the manufacturer does not want to
|
|
publish it on its corporate Web site or distribute it monthly in an external
|
|
report. By exploiting the public Internet, you can easily establish a virtual
|
|
private network (VPN) to meet the needs of both companies.</p>
|
|
</div>
|
|
<div class="section" id="rzajabpscenario__objective"><a name="rzajabpscenario__objective"><!-- --></a><h4 class="sectionscenariobar">Objectives</h4><p>In
|
|
this scenario, MyCo wants to establish a VPN between a host in its parts division
|
|
and a host in the manufacturing department of one their business partners,TheirCo.</p>
|
|
<p>Because
|
|
the information these two companies share is highly confidential, it must
|
|
be protected while it travels across the Internet. In addition, data must
|
|
not flow in the clear within either company's networks because each network
|
|
considers the other untrusted. In other words, both companies require end-to-end
|
|
authentication, integrity, and encryption.</p>
|
|
<div class="important"><span class="importanttitle">Important:</span> The intent
|
|
of this scenario is to introduce, by example, a simple host-to-host VPN configuration.
|
|
In a typical network environment, you will also need to consider firewall
|
|
configuration, IP addressing requirements, and routing, among others.</div>

<li>iSeries-A has an IP address of 10.6.1.1. This is the connection endpoint,

as well as the data endpoint. That is, iSeries-A performs IKE negotiations

tasks</h4><p>You must complete each of these tasks to configure the business

<div class="note"><span class="notetitle">Note:</span> Before you start
|
|
these tasks verify the TCP/IP routing to ensure that the two gateway servers

can communicate with each other across the Internet. This ensures that hosts

|
on each subnet route properly to their respective gateway for access to the

|
remote subnet.</div>
