ADSL X4 User Guide
Using IP Filters
Use the
IP Filter Configuration
page to set up IP filters to allow
or block traffic coming into your computer from the Internet. To
open this page, click the
IP Filtering
button in the
Configuration
section of the
Advanced Setup
page.
To filter Internet traffic, you must define one or more rules (that is,
criteria you want the information to meet before it can proceed).
As information comes in from the Internet, the X4 examines it
and—if it meets the rule—moves forward to its destination on
your computer or network. If it does not, it is discarded.
The rule can be based on many characteristics, including the
network or Internet protocol it carries, IP address of the sending
computer, the port that the traffic is coming in on, and so forth.
Once you have set up the IP filters you want, click the
Save
Changes
button, and then click the
Write Settings to Flash
button.
For more information about setting up IP filters, click the
Help
icon at the top of the screen while you are on the
IP Filter
Configuration
page. This opens the online help and displays a
topic containing detailed information about this process.
