Brute-Force Password Guessing Protection
The Contivity 221 has a special protection mechanism to discourage brute-force
password guessing attacks on the Contivity 221's management interfaces. You can
specify a wait-time that must expire before entering a fourth password after three
incorrect passwords have been entered. Please see the appendices for details about
this feature.
Content Filtering
The Contivity 221 can block web features such as ActiveX controls, Java applets
and cookies, as well as disable web proxies. The Contivity 221 can block specific
URLs by using the keyword feature. It also allows the administrator to define time
periods and days during which content filtering is enabled.
Packet Filtering
The packet filtering mechanism blocks unwanted traffic from entering/leaving
your network.
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the Contivity 221 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 via a familiar "dial-up networking" user
interface.
PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables
secure transfer of data from a remote client to a private server, creating a Virtual
Private Network (VPN) using a TCP/IP-based network.
PPTP supports on-demand, multi-protocol and virtual private networking over
public networks, such as the Internet. The Contivity 221 supports one PPTP server
connection at any given time.
