ADSL X4 User Guide 

Use the Firewall Configuration page to change the X4’s firewall 
settings. To open this page, click the Firewall button in the 
Configuration section of the Advanced Setup page. 
When you install the X4, a firewall is automatically established to 
offer your computer protection as you use the Internet. (This 
built-in firewall is in addition to the NAT settings on your X4.) 
By default, the firewall is set up to be relatively strict – that is, the 
only Internet traffic it allows to access your computer is that which 
you are likely to need (for example, a Web page you request in your 
browser’s address bar). 
For most users, this access is secure and sufficient. Most users will 
never need to change their firewall settings. 
However, use the Firewall Configuration page if you want to: 
•  Blacklist computers that try to hack into your computer or 

network so that they are denied access. (By default, this feature 
is disabled.) 

•  Have email sent if your computer or network is attacked by an 

outside computer. 

Once you have made the changes you want on this page, click the 
Save Changes button, and then click the Write Settings to Flash 
button. 
For details about the individual firewall settings you can specify, 
click the Help icon at the top of the screen while you are on the 
Firewall Configuration page. This opens the online help and 
displays a topic containing detailed information about the X4’s 
firewall settings.
