Applications
• Shared IP Address
The Wireless 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 Wireless 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 Wireless 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 Wireless 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 Wireless 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. WEP (Wired Equivalent
Privacy), SSID, and MAC filtering provide security over the wireless network.
