How to add Windows Firewall exception

1. Access "Control Panel" in Windows

You need to right-click on the lower-left corner of the screen and then click "Control Panel".

2. Click "System and Security"

3. Click "Windows Firewall"

4. Find the link on the left side of the screen, "Allow an app or feature through Windows Firewall".

5. Click "Change settings" located above the list of apps and features.

Note that you need to be logged in as an administrator.

6. Change the settings to allow the app.

In this case, let's go ahead and allow "the SecurityKISS Tunnel" through the Private and Public networks. In this case, it is only allowed through the Public network. If you check the Private network and click "OK" at the bottom of the window, we will be able to pass through the firewall on the Public network. So, set those settings according to your preference, and then you can close this window.
