General Security Level Settings

Use the 'Security Settings' screen to configure the Telephone Adapter's basic security

The firewall regulates the flow of data between the home network and the Internet. Both
incoming and outgoing data are inspected and then either accepted (allowed to pass
through the MP-202) or rejected (barred from passing through the MP-202) according to a
flexible and configurable set of rules. These rules are designed to prevent unwanted
intrusions from the outside, while allowing home users access to the Internet services that
they require.
The firewall rules specify what types of services available on the Internet may be accessed
from the home network and what types of services available in the home network may be
accessed from the Internet. Each request for a service that the firewall receives, whether
originating in the Internet or from a computer in the home network, is checked against the
set of firewall rules to determine whether the request should be allowed to pass through the
firewall. If the request is permitted to pass, then all subsequent data associated with this
request (a "session") will also be allowed to pass, regardless of its direction.
