• Shared IP Address
The Barricade ADSL Router provides Internet access for up to 253
users via a single shared IP address. Using only one ISP account,
multiple users on your network can browse the web at the same time.
• Virtual Server
If you have a fixed IP address, you can set the Barricade ADSL Router
to act as a virtual host for network address translation. Remote users
access various services at your site using a constant IP address. Then,
depending on the requested service (or port number), the Barricade
ADSL Router can route the request to the appropriate server (at
another internal IP address). This secures your network from direct
attack by hackers, and provides more flexible management by allowing
you to change internal IP addresses without affecting outside access
to your network.
• DMZ Host Support
Allows a networked computer to be fully exposed to the Internet.
This function is used when NAT and firewall security prevent an
Internet application from functioning correctly.
• Security
The Barricade ADSL Router supports security features that deny
Internet access to specified users, or filter all requests for specific
services that the administrator does not want to serve. The Barricade
ADSL Router’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.
