The options in the Firewall menu allow the administrator to control and manage the features of the
DFL-160 that are specific to a firewall. A firewall, as the name suggests, is a capability that
provides a protective barrier against a range of potential threats that can be transported by the public
Internet towards sensitive internal networks.
Using the DFL-160 as a Firewall
The firewalling capabilities of NetDefendOS allow the administrator to impose various security
restrictions on the traffic flowing through the interfaces of the DFL-160. In summary, the
firewalling options are:
• The types of traffic that are allowed to flow between interfaces can be specified and also in what
direction they are allowed to flow.
• Secure VPN connections can be specified for traffic flowing through interfaces.
• Policies can be set for the URLs to which web surfing is allowed.
