ESSID Broadcast
Many wireless network adapters currently on the market possess
a feature known as site survey. It scans the air for any available
network and allows each computer to automatically select a network
from the survey. This occurs if the computer’s SSID is set to “ANY”.
Your Belkin Router can block this random search for a network. If
you disable the “ESSID Broadcast” feature, the only way a computer
can join your network is by its SSID being set to the specific name of
the network (like WLAN). Be sure that you know your SSID (network
name) before enabling this feature. It is possible to make your
wireless network nearly invisible. By turning off the broadcast of the
SSID, your network will not appear in a site survey. Obviously, turning
off the broadcast feature of the SSID helps increase security.
Encryption
Setting encryption can help keep your network secure. The Router
uses Wired Equivalent Privacy (WEP) encryption to protect your data
and features two rates of encryption: 64-bit and 128-bit. Encryption
works on a system of keys. The key on the computer must match the
key on the Router, and there are two ways to make a key. The easiest
is to let the Router’s software convert a passphrase you’ve created
into a key. The advanced method is to enter the keys manually.
Virtual Servers
This function will allow you to route external (Internet) calls for
services such as a web server (port 80), FTP server (Port 21), or other
applications through your Router to your internal network. Since your
internal computers are protected by a firewall, machines from the
Internet cannot get to them because they cannot be “seen”. If you
need to configure the virtual server function for a specific application,
you will need to contact the application vendor to find out which port
settings you need.
To manually enter settings, enter the IP address in the space provided
for the internal machine, the port type (TCP or UDP), and the LAN
and public port(s) required to pass. Then select “Enable” and click
“Set”. You can only pass one port per internal IP address. Opening
ports in your firewall can pose a security risk. You can enable and
disable settings very quickly. It is recommended that you disable the
settings when you are not using a specific application.
