Using Firewall Protection
Connection type and detections of incoming communications
Connection type and detections of incoming communications
Firewall protection monitors communications coming into the network (known as inbound events) to
determine whether they meet criteria specified for safe communications. If an event does not meet
the criteria, it is blocked from reaching computers on the network.
Specify criteria by selecting the type of connection client computers are using. A policy option setting
determines whether the administrator or the user selects the connection type.
Types of connections
The connection type defines the environment where client computers are used, It determines what
firewall protection considers to be suspicious activity and, therefore, which IP addresses and ports are
allowed to communicate with the network computers.
Select from three connection environments.

Additional information about connection types
It is important to update the connection type whenever the working environment changes. For
example, mobile users who connect to both secured (trusted) and unsecured (untrusted) networks
must be able to change their setting accordingly.
A policy option specifies whether firewall protection tracks blocked events for reporting purposes.
When the option is enabled, you can see a listing of all blocked events in the report entitled Inbound
Events Blocked by Firewall.
The connection type does not affect the way that firewall protection handles detections of Internet
applications running on client computers.
