An application is blocked by the firewall, how can I change that?

Instructions

Problem description

You cannot use specific applications like Internet Explorer, Outlook or another application that uses the Internet. When you disable your NSS firewall, the applications react normally again.

Follow this procedure to solve the problems with the firewall and the denied applications.

Solution

Cause of the blockade

A firewall is meant to block or allow the access to the Internet for applications. The firewall also blocks incoming connections to your computer, made by computers that are connected to the Internet.

If your firewall detects a change in any of the applications, it warns you about it and asks whether or not to grant the changed application access to the Internet.

The procedure described below will help you to change the state of denied applications to again allow them to access the Internet.

Procedure

  1. Right-click the N icon to open a list of actions.
