<h1 class="topictitle1">Virtual Private Networking (VPN)</h1>
|
||
|
<div><p>A virtual private network (VPN) allows your company to securely
|
||
|
extend its private intranet over the existing framework of a public network,
|
||
|
such as the Internet. With VPN, your company can control network traffic while
|
||
|
providing important security features such as authentication and data privacy.</p>
|
||
|
<p>VPN is an optionally-installable component of <span class="keyword">iSeries™ Navigator</span>,
|
||
|
the graphical user interface (GUI) for <span class="keyword">i5/OS™</span>.
|
||
|
It allows you to create a secure end-to-end path between any combination of
|
||
|
host and gateway. VPN uses authentication methods, encryption algorithms,
|
||
|
and other precautions to ensure that data sent between the two endpoints of
|
||
|
its connection remains secure.</p>
|
||
|
<p>VPN runs on the network layer of the TCP/IP layered communications stack
|
||
|
model. Specifically, VPN uses the IP Security Architecture (IPSec) open framework.
|
||
|
IPSec provides base security functions for the Internet, as well as furnishes
|
||
|
flexible building blocks from which you can create robust, secure virtual
|
||
|
private networks.</p>
|
||
|
<p>VPN also supports Layer 2 Tunnel Protocol (L2TP) VPN solutions. L2TP connections,
|
||
|
which are also called virtual lines, provide cost-effective access for remote
|
||
|
users by allowing a corporate network server to manage the IP addresses assigned
|
||
|
to its remote users. Further, L2TP connections provide secure access to your
|
||
|
system or network when you protect them with IPSec.</p>
|
||
|
<p>It is important that you understand the effect a VPN will have on your
|
||
|
entire network. Correct planning and implementation are essential to your
|
||
|
success. Review these topics to ensure that you know how VPNs work and how
|
||
|
you might use them:</p>
