Network Interface Overview

The Network Interface allows you to configure network settings for the SonicWALL CDP Appliance.

 

Settings

Provides access to configuration options, including IP address, subnet mask, default gateway IP address and interface, name servers, and hostname and domain.

Connectivity

Provides access to options for testing connectivity, including pinging the registration server, pinging a URL and resolving a URL.

Configuring Network Settings

The Network > Settings page allows you to configure your SonicWALL CDP appliance to communicate with your network.

 
Note
For initial setup of your SonicWALL CDP appliance, see the SonicWALL CDP Getting Started Guide for your model.

This section contains the following subsections:

 
•
“Configuring Appliance Host Name and Domain” section
 
•
“Configuring IP, Subnet, and Gateway Addresses” section
 
•
“Configuring the Domain Name Server Address” section

Configuring Appliance Host Name and Domain

The Summary tab located on the Networks > Settings page allows the administrator to configure the host name, domain, and friendly name for the SonicWALL CDP appliance.

Step 1
Point the browser on your management computer to the SonicWALL CDP Web Management Interface and navigate to Network > Settings in the left-hand menu and select the Summary tab.
Step 2
Type the host name for the SonicWALL CDP appliance into the Name field.
Step 3
Type the domain name for the appliance into the Domain field.
Step 4
Type a descriptive name for the appliance into the Friendly Name field.
Step 5
Click the Apply button.

Configuring IP, Subnet, and Gateway Addresses

The Interface tab located on the Networks > Settings page allows the administrator to configure the IP address, subnet address, and gateway address for the SonicWALL CDP appliance.

Step 1
Navigate to Network > Settings in the left-hand menu. Select the Interface tab and click the Configure icon in the table.

 

Step 2
Specify a name for the interface in the iface field.

 

Step 3
Specify the IP Address in the ip field by entering an unused static IP address within range of your local subnet.
Step 4
Enter your subnet mask in the netmask field.

Using an IP address within the range of a local subnet is accomplished by keeping the network portion, according to the subnet mask, of the LAN gateway IP address the same. For example, if your gateway IP address is 10.10.10.1 and your subnet mask is 255.255.255.0 , you can set your SonicWALL CDP appliance IP address to 10.10.10.20 .

Step 5
Enter the default gateway address in the gateway field. The gateway is typically a firewall in your subnet that also has access to the Internet.
Step 6
Click Save .
 
Note
You may lose connectivity with the SonicWALL CDP appliance during an IP address change. This occurs because the SonicWALL CDP appliance is now on a different subnet than the management computer. To reconnect, point your browser to the new IP address (http://<new IP address>).

Configuring the Domain Name Server Address

You must configure the correct Domain Name Server (DNS) address settings in order to register and use your SonicWALL CDP appliance. The DNS must be able to resolve external Internet names.

Step 1
Navigate to Network > Settings in the left-hand menu. Select the Name Server tab.

 

Step 2
Click the Add button located in the lower-right, below the Name Server table.

 

Step 3
Enter a single Domain Name Server in the server field and click Save . Repeat steps 2 and 3 to add additional DNS entries if more DNS entries are desired.

New Domain Name Servers are now available in the Server list. To remove a domain name server, click the X button next to the server.

Testing Network Connectivity

You can test the network connectivity, trace routes, test connectivity to a certain URL, and resolve URLs on the Network Connectivity page. For detailed information, see the following sections:

 
•
“Checking Network Settings” section
 
•
“Tracing Network Routes” section
 
•
“Testing URL Connectivity” section
 
•
“Resolving URLs” section

Checking Network Settings

General network connections such as the default gateway and DNS servers can be tested on the Check Network Settings tab. You can also test the connectivity to the SonicWALL license manager.

To check the network connections, perform the following steps:

Step 1
Navigate to Network > Connectivity and click on the Check Network Settings tab.

 

Step 2
Locate the General Network Connection you wish to test. For this example, the Default Gateway is used.

 

Step 3
Click on the Test button located to the right of the desired connection to be tested.
Step 4
The test results column will display the results of the network connection test.
 
•
If the test was successful, Ping succeeded is visible.
 
•
If the network connection test failed, Ping failed is visible.

Tracing Network Routes

You can type in a URL on the Trace Route tab to find out the network route that traffic from the SonicWALL CDP appliance takes to reach that location.

To trace the route to a particular URL, perform the following steps:

Step 1
Navigate to Network > Connectivity and click on the Trace Route tab.

 

Step 2
In the text box near the top of the page, type in an IP address or a URL in the form of “mysonicwall.com”.
Step 3
Click the Trace URL button. If the trace is successful, the IP address of each hop is displayed, beginning with the network device closest to the SonicWALL CDP and ending with the one closest to the target URL. The status indicator at the bottom of the window displays “Succeeded” and shows the number of milliseconds it took to trace the route.

If the URL is unreachable, the status message at the bottom of the window indicates the failure of the trace.

Testing URL Connectivity

You can test the connectivity to a certain URL by typing it in on the Test URL tab. If the test succeeds, you know that the SonicWALL CDP appliance can reach that location.

To test the connectivity to a particular URL, perform the following steps:

Step 1
Navigate to Network > Connectivity and click on the Test URL tab.
Step 2
Type the URL you wish to test into the text field, either as an IP address or in the form “mysonicwall.com”. To test connectivity from the SonicWALL CDP appliance to the default URL, sonicwall.com, you can leave the field blank.
Step 3
Click the Test URL button. If the appliance can connect to the URL, the status indicator at the bottom of the window displays “Succeeded” and shows the number of milliseconds it took to connect.

If the appliance cannot connect to the URL, the status indicator displays “failed”.

Resolving URLs

You can resolve a URL to find out its IP address(es) by typing in the URL on the Resolve URL tab.

To resolve a URL, perform the following steps:

Step 1
Navigate to Network > Connectivity and click on the Resolve URL tab.
Step 2
Type the URL you wish to resolve into the text field, in the form “mysonicwall.com”. To test connectivity from the SonicWALL CDP appliance to the default URL, sonicwall.com, you can leave the field blank.
Step 3
Click the Resolve URL button. If the appliance can resolve the URL, the status indicator at the bottom of the window displays one or more IP addresses for the URL.

If the appliance cannot connect to the URL, the status indicator displays “failed”.
