Configure Web Filter and Firewall in Internet Security

The  following instructions are extracted from the Threat Track Security knowledgebase for VIPRE Internet Security, and have been customized to apply to CTI Navigator Desktop.

You can determine whether VIPRE's Web Filter or its Firewall is causing the problem by attempting to run the application when either is disabled. You should disable the Web Filter alone as your first attempt to identify the problem, and then disable the firewall all together. Once the component has been identified, enter an exception rule using the following instructions.

Otherwise, disable VIPRE's firewall and enable your Windows Firewall. Only one firewall should be active at a time.

VIPRE 2015b (new interface) - 2016

To add exceptions to your VIPRE 2015 or 2016 Firewall (so they will not be blocked from Internet access)

1. Open the VIPRE Interface
2. Click Manage tab > Firewall
3. Scroll all the way down until you see Firewall Default Behaviors
4. Change the settings to Learning Mode

5. A notification labeled "Firewall Learning Mode" will prompt you to confirm action, place a check in the Delete custom rules, too option and click Reset button. This will erase all custom made rules and reset the firewall back to default

6. Open CTI Navigator again and you should be prompted with VIPRE notification about allowing the application to communicate to your computer over the network. Click Trust Location or put a check mark under the Male A rule box and click Allow for VIPRE to make an exception.

7. Navigator should now be able to access the Internet. Once this is completed, change the firewall settings back to Standard Mode so that VIPRE will apply the rule and not ask your permission every time you try to access the same connection.

VIPRE 2013 - 2015a ("Overview" Home screen)

1. Open the VIPRE "Overview" User Interface
2. Open the Firewall Settings windows by clicking Settings next to the FIREWALL section
3. Click the Exceptions button and click the Add button
4. Enter the path to where CTI Navigator Desktop is installed on this computer.
   • In a 64-bit version of Windows, the path is  C:\Program Files (x86)\CTI Navigator\Cti Navigator.exe;
   • In a 32-bit version of Windows, the path is  C:\Program Files\CTI Navigator\Cti Navigator.exe
5. Select Allow for Trusted Inbound and Outbound.
6. Click OK.

Web Filter Application Exception (applies only to versions prior to VIPRE Internet Security 2013)

1. From the Firewall settings window, click the Web Filter Settings button
2. Select the Allowed Applications tab and click the Add button
3. Enter the path to where CTI Navigator,exe is installed on this computer (see above)
4. Click OK.

At this point the exceptions will be applied and the application should now work without an issue.

Executable is unknown or not found

If you are not sure what file needs to be added to the exception list to allow the application to function (such as CTI Navigator.exe and/or CTIUPDManager.exe), you can try to switch the firewall to learning mode in order to find this information:

1. Open the VIPRE user interface
2. Click Settings and go to the Firewall tab
3. Click Reset to Defaults and in the new menu that pops up select Reset to Learning Mode and click OK
4. Click OK again to exit the settings window

Try running the application you are trying to run once again and you should get a prompt from VIPRE about allowing the application to communicate over the internet. Place a check mark in the option "Take the action I choose in the future (create a rule)" and the exception should be created in the firewall exceptions list. Now if you click on the Edit Settings option for the VIPRE Firewall and check the Exceptions list, you will see a new or several new items (depending on how many items you allowed and created a rule for) listed. Once this has been completed, you can change the setting in 'Reset to Defaults' to 'Reset to Simple Mode'.

Internet access has been blocked or application is still blocked

It is likely that the Network on which you are connected was blocked at some point by the firewall and is no longer trusted. In this scenario, the easiest thing to do is to reset the firewall to default settings:

1. Open the VIPRE Premium user interface and proceed to the File menu at the top
2. Click Settings and go to the Firewall tab
3. Click Reset to Defaults and in the new menu that pops up select Reset to Simple Mode or Reset to Learning Mode
4. Place a check in the Delete all user defined rules option

1. Using the instructions under Firewall Application and Port Exceptions that are listed above, make an application exception for C:\Windows\System32\svchost.exe. Make sure that it is set to allow for trusted connections.
2. Also make a port exception on the RDP port for this same application. The name can be whatever you choose, but the application should be C:\Windows\System32\svchost.exe, the Port Number must be 2289 (or whatever you have the RDP port set as), and the Protocol must be TCP.
