<h1 class="topictitle1">Create NAT rules</h1>
|
|
<div><p>To use network address translation (NAT), you <em>must</em> define
|
|
nicknames for the IP addresses you intend to use.</p>
|
|
<div class="section"><p>You cannot create NAT rules with the standard 32-bit address notation.
|
|
Rather than specifying a real address such as 193.112.14.90, you must refer
|
|
to 193.112.14.90 by a <em>name</em>. The system associates the name you defined
|
|
with the corresponding addresses and translates them accordingly. Therefore,
|
|
you must define your addresses before your system can apply NAT rules to them. </p>
|
|
</div>
|
|
<div class="section"><p>The Packet Rules Editor allows you to create two types of NAT
|
|
rules. One type allows you to hide addresses, while the other type allows
|
|
you to map addresses. </p>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">Hide Addresses</h4><p>Hide addresses when you want to keep
|
|
your private addresses hidden from public view. A hidden address rule allows
|
|
you to hide multiple internal addresses behind a single public IP address.
|
|
This type of NAT is also known as <em>masquerade</em> NAT.</p>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">Map Addresses</h4><p>Map addresses when you want to route
|
|
traffic from a single public IP address into a single internal address. This
|
|
type of NAT is also known as <em>static</em> NAT.</p>
|
|
</div>
|
|
<div class="section"><p>For instructions on how to hide or map addresses,
|
|
use the Packet Rules Editor online help. </p>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">Next Topic</h4><p>If you plan to filter traffic flowing
|
|
into and out of your network, go to Create IP filter rules. Otherwise, proceed
|
|
to <a href="rzajbrzajb89commentssd.htm">Add comments in the packet rules</a>.</p>
