5 Dell Networking Testing and Validation
Now that the networking equipment has been configured to allow guest and employee access to their
online resources, we will test and validate the areas of concern.
Step 1
Connect to the G_TestX (X is station number) WLAN in Windows Network and Sharing Center. Once you
have connected, open chrome and enter the ip address 1.1.1.1 (or any other ip address). This demonstrates
the fact that the IAP will redirect the guest user to the IAP captive portal splash page on any access
attempt. Click on Accept and you will be redirected to the public internet site of the Guest network.

36
Step 2
By accessing this website, this proves that the Guest network on the IAP can reach the internet through
the X-Series switch and the SonicWALL firewall. The ip address 10.1.100.101 in the Chrome url bar is the
same ip address entered in for the URL Redirect on the Security tab for step 10 during the IAP Guest
network configuration. This setting can also be used to direct to an internal home page.

37
Step 3
In the Chrome browser enter the ip address 172.20.100.100. This is the corporate data center web server
for the Employee network, accessed through the VPN. This webpage will not be accessible by the Guest
user due to the topology of this lab configuration. Administrators can further protect their network by
implementing policies and zones within the firewall.

38
Step 4
Disconnect from the Guest network (G_TestX) WLAN and connect to the Employee network (E_TestX)
WLAN. Open the chrome browser, enter the ip address 172.20.100.100 if it is not already there. This ip
address allows employee to access to the internal data center web server.

39
Step 5
Enter the ip address 10.1.100.101. This is the same public internet site that the Guest users were able to
access.
Step 6
Login to the SonicWALL TZ300 admin page at the ip address 172.20.X.2 (X is station number)
Reminder> username:admin password:password
On the menu click on Firewall, then go to App Control Advanced. Under App Control Global Settings
 Check Enable App Control
 Check Enable Logging For All Apps
Click Accept.
Note: the ip management interface was enabled for all three interfaces, admin, employee, and guest.

40
Step 7
TIME CHECK- The app control policy has already been configured for you. If you have time, follow steps
7, 8, and 9 to discover what the policy settings look like. If you’re limited on time, skip to step 10.
In the App Control Page, scroll down to App Control Advanced and click on the Category drop down
menu. Choose FILETYPE-DETECTION, click on the Configure icon for Image.

41
Step 8
In the Image configuration settings:
 Block: Enable
 Log: Enable
 Included Users/Groups: All (Admin, Employee, and Guest)
 Included IP Address Range: All
Click Cancel when you are finished reviewing the settings.

42
Step 9
Under the App Control Advanced section, in View Style: click on the Application drop down menu and
choose Image, next click on the Viewed By: drop down menu and choose Signature. We can now see
what image file types the advanced app control is filtering or blocking.

43
Step 10
Logout of the SonicWALL. Open a new browser window. In the Chrome browser click on the Clear Cache
button on the bookmark bar then click on the Clear browsing data button.

44
Step 11
In the Chrome URL field enter the ip address 10.1.100.101. With the SonicWALL firewall image app control
enabled the .gif and .jpg images on the public internet web page are being blocked.

45
Step 12.
Log back in to the SonicWall firewall. In the SonicWALL menu scroll down to Log, click on it to expand its
sub-menu choices and then click on Log Monitor. In the Log Monitor entries, there will be two
Application Control Firewall Alerts for GIF and JPEG HTTP download attempts.
