Security

MP-20x's security suite includes comprehensive and robust security services: Stateful
Packet Inspection Firewall, user authentication protocols and password protection
mechanisms. These features together allow users to connect their computers to the
Internet and simultaneously be protected from the security threats of the Internet.
The firewall, which is the cornerstone of your Telephone Adapter's security suite, has been
exclusively tailored to the needs of the residential/office user and has been pre-configured
to provide optimum security.
MP-20x firewall provides both the security and flexibility that home and office users seek. It
provides a managed, professional level of network security while enabling the safe use of
interactive applications, such as Internet gaming and video-conferencing.
Additional features, including surfing restrictions and access control, can also be easily
configured locally by the user through a user-friendly Web-based interface, or remotely by
a service provider.
MP-20x firewall supports advanced filtering, designed to allow comprehensive control over
the firewall's behavior. You can define specific input and output rules, control the order of
logically similar sets of rules and make a distinction between rules that apply to WAN and
LAN network devices.
The Web-based management screens in the Security section feature the following:
The 'General' screen allows you to choose the security level for the firewall (refer to'
General Security Level Settings' on page 178).
The 'Access Control' screen can be used to restrict access from the home network to
the Internet (refer to 'Local Servers (Port Forwarding)' on page 182).
The 'Port Forwarding' screen can be used to enable access from the Internet to
specified services provided by computers in the home network and special Internet
applications (refer to 'Port Forwarding' on page 182).
The 'DMZ Host' screen allows you to configure a LAN host to receive all traffic arriving
at your Telephone Adapter, which does not belong to a known session (refer to' Port
Triggering' on page 186).
The 'Port Triggering' screen allows you to define port triggering entries, to dynamically
open the firewall for some protocols or ports. (refer to 'Remote Administration' on page
243).
