Brute force password guessing protection
The Business Secure Router has a special protection mechanism to discourage
brute force password guessing attacks on the Business Secure Router management
interfaces. You can specify a wait time that must expire before you can enter a
fourth password after entering three incorrect passwords.
Content filtering
The Business Secure Router can block web features such as ActiveX controls,
Java applets, and cookies, as well as disable web proxies. The Business Secure
Router can block specific URLs by using the keyword feature. The administrator
can also define time periods and days during which content filtering
is enabled.
Packet filtering
The packet filtering mechanism blocks unwanted traffic from entering or leaving
your network.
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the Business Secure Router and other
UPnP-enabled devices can dynamically join a network, obtain an IP address, and
convey its capabilities to other devices on the network.
Call scheduling
Configure call time periods to restrict and allow access for users on remote nodes.
PPPoE
PPPoE facilitates the interaction of a host with an Internet modem to achieve
access to high-speed data networks through a familiar dial-up networking user
interface.
