Cisco Cisco Content Security Management Appliance M390 User Guide

Enter the network mask and IP address of the default router (gateway) on your network.

Next, configure the Domain Name Service (DNS) settings. AsyncOS contains a high-performance 
internal DNS resolver/cache that can query the Internet’s root servers directly, or the system can use 
DNS servers that you specify. If you use your own servers, you need to supply the IP address of each 
DNS server. You can enter up to four DNS servers when you are using the System Setup Wizard.

The DNS servers you specify have an initial priority of 0. For more information, see the 

.

The appliance requires access to a working DNS server to perform DNS lookups for incoming 
connections. If you cannot specify a working DNS server that is reachable by the appliance while you 
are setting up the appliance, you can select Use Internet Root DNS Servers, or else temporarily specify 
the IP address of the Management interface so that you can complete the System Setup Wizard.

Now, the System Setup Wizard displays a summary of the setup information that you have entered. If 
you need to make any changes, click Previous at the bottom of the page and edit the information.

After you have reviewed the information, click Install This Configuration. Then click Install in the 
confirmation dialog box that appears.

If the page appears not to respond when you click Install This Configuration, this is because the 
appliance is now using the the new IP address that you specified in the wizard. To continue using the 
appliance, use the new IP address. If you followed the instructions in the Quick Start Guide to 
temporarily change the IP address of the computer you used to access your new hardware appliance, 
revert your computer’s IP address to its original settings first. 

After you install the Security Management appliance and run the System Setup Wizard, you can modify 
other settings on the appliance and configure the monitoring services. 

Depending on the process you used to access the appliance in order to run the system setup wizard, the 
System Setup Next Steps page appears. If this page dos not appear automatically, you can access it by 
choosing Management Appliance > System Administration > Next Steps. 

Click on any of the links on the System Setup Next Steps page to proceed with the configuration of your 
Cisco Content Security appliances. 

You will add managed Email and Web Security appliances to the Security Management appliance when 
you configure the first centralized service for each appliance. 

Supported Email and Web Security appliances are shown in the 

. 

When you add a remote appliance, the Security Management appliance compares the product name of 
the remote appliance with the type of appliance you are adding. For example, you add an appliance using 
the Add Web Security appliance page, the Security Management appliance checks the product name of
