<h1 class="topictitle1">Activate packet rules</h1>
|
|
<div><p>Activating the packet rules that you create is the final step in
|
|
configuring packet rules.</p>
|
|
<div class="section"><p>You must activate, or load, the rules that you created in order
|
|
for them to work. However, before you activate your rules you should verify
|
|
that they are correct. Always attempt to resolve any problems before activating
|
|
your packet rules. If you activate rules that have errors or that are ordered
|
|
incorrectly, your system will be at risk. Your system has a verify function
|
|
that is automatically invoked any time you activate your rules. Because this
|
|
automatic feature only checks for major syntactical errors, you should not
|
|
rely solely on it. Make sure to always manually check for errors in your rules
|
|
files as well.</p>
|
|
<p>When filter rules are not applied to an interface (for
|
|
example, you are only using NAT rules, not filtering rules), a warning (TCP5AFC)
|
|
appears. This is not an error. It only verifies whether using one interface
|
|
is your intention. Always look at the last message. If it says
|
|
the activation is successful, then the messages above it are all warnings. </p>
|
|
<div class="note"><span class="notetitle">Note:</span> When
|
|
you activate new rules on all interfaces, they replace all previous rules
|
|
on all physical interfaces. Even if a physical interface is not mentioned
|
|
in the new rules, it will be replaced. However, if you choose to activate
|
|
new rules on a specific interface, the rules will only replace the rules on
|
|
that specific interface. Existing rules on other interfaces will be untouched.</div>
|
|
<p>After
|
|
your packet rules have been configured and activated, you might need to periodically
|
|
manage them to ensure the security of your system. </p>
