Firewall Tasks > Common Tasks - View Active Connections

The Active Connections interface contains an at-a-glance summary of all currently active connections on a per-application basis. You can view all the applications that are connected; all the individual connections that each application is responsible for; the direction of the traffic; the source IP and port and the destination IP and port. You can also see the total amount of traffic that has passed in and out of your system over each connection.

This list is updated in real time whenever an application creates a new connection or drops an existing connection. The View Active Connections is an extremely useful aid when testing firewall configuration; troubleshooting new firewall policies and rules;  monitoring the connection activity of individual applications and your system as a whole and for terminating any unwanted connections.
