Shared IP Address
The 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 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 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 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 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.
