User-Definable Application Sensing Tunnel
You may define special applications that require multiple connections
such as Internet gaming, video conferencing, and Internet telephony.
The Barricade will then sense the application type and open a
multi-port tunnel for it.
•
DMZ Hosts Support
Allows a networked computer to be fully exposed to the Internet.
This function is used when the special application sensing tunnel
feature is insufficient to allow an application to function correctly.
•
Security
The Barricade supports security features that deny Internet access to
specified users, or drop requests for specific services. The Barricade’s
firewall also blocks common hacker attacks, including IP Spoofing,
Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP
port loopback, Snork Attack, TCP null scan, and TCP SYN flooding.
•
Virtual Private Network
The Barricade supports three of the most commonly used VPN
protocols – PPTP, L2TP, and IPSec. These protocols allow remote
users to establish a secure connection to their corporate network. If
your service provider supports VPNs, then any of these protocols can
be used to create an authenticated and encrypted tunnel for passing
secure data over the Internet (i.e., a traditionally shared data network).
The VPN protocols supported by the Barricade are briefly described
below.
