<div><p>There are several steps you must take to plan how DHCP should be
|
||
|
|
set up for your network.</p>
|
||
|
|
<div class="section"><p>Setting up DHCP can be a time-consuming and error-prone process
|
||
|
|
if you have not taken the time to plan how your DHCP server should be configured.
|
||
|
|
By taking time to think about your network setup and security concerns in
|
||
|
|
advance, you can configure your DHCP server more efficiently. The following
|
||
|
|
topics pose some important questions that you should consider before you configure
|
||
|
|
DHCP in your network.</p>
|
||
|
|
<dl><dt class="dlterm">Network topology considerations</dt>
|
||
|
|
<dd>You can plan for the majority of the DHCP setup just by looking at your
|
||
|
|
network topology, the devices on the network (for example, routers), and how
|
||
|
|
you want to support your clients in DHCP.</dd>
|
||
|
|
<dt class="dlterm">Security considerations</dt>
|
||
|
|
<dd>The DHCP protocol is not capable of verifying that clients requesting
|
||
|
|
IP addresses are authorized to do so. Because of the nature of DHCP's interaction
|
||
|
|
to the network, it is important that you secure your iSeries™ server from outside clients.
|
||
|
|
If your DHCP server is on an iSeries server that is part of a trusted internal
|
||
|
|
network, you might be able to use <a href="../rzajb/rzajbrzajb0ippacketsecuritysd.htm">Packet rules (filtering and NAT)</a> to further secure it
|
||
|
|
from any unauthorized parties. If your DHCP server is on an iSeries server
|
||
|
|
that is attached to an untrusted network, such as the Internet, refer to <a href="../rzaj4/rzaj4secoverview.htm"> iSeries and
|
||
|
|
Internet security</a>. For more security references, see the <a href="../rzahg/rzahgicsecurity.htm">Security</a> topic
|
||
|
|
in the information center.</dd>
