The Firewall Tab - General
When you click the Security tab, you will see the General screen. The Router’s firewall enhances the security of
your network. You can implement a Stateful Packet Inspection (SPI) firewall, block anonymous Internet requests,
and enable block mechanisms.
General
DoS Prevention. Denial of Service (DoS) Prevention checks incoming packets before allowing them to enter your
network. To use this feature, select Enabled from the drop-down menu. If you do not want DoS Prevention, select
Disabled.
Internet Block
Block Anonymous Internet Requests. This keeps your network from being “pinged” or detected and reinforces
your network security by hiding your network ports, so it is more difficult for intruders to work their way into your
network. Select Enabled to block anonymous Internet requests, or Disabled to allow anonymous Internet
requests.
Block Multicast. Multicasting allows for multiple transmissions to specific recipients at the same time. If
multicasting is permitted, then the Router will allow IP multicast packets to be forwarded to the appropriate
computers. Select Enabled to filter multicasting, or Disabled to disable this feature.
Web Block
Proxy. Use of WAN proxy servers may compromise the Router's security. Denying Filter Proxy will disable access
to any WAN proxy servers. To enable proxy filtering, click Enabled.
Java. Java is a programming language for websites. If you deny Java applets, you run the risk of not having
access to Internet sites created using this programming language. To enable Java applet filtering, click Enabled.
ActiveX. ActiveX is a programming language for websites. If you deny ActiveX, you run the risk of not having
access to Internet sites created using this programming language. To enable ActiveX filtering, click Enabled.
Cookies. A cookie is data stored on your PC and used by Internet sites when you interact with them. To enable
cookie filtering, click Enabled.
When you have finished making changes to the screen, click the Save Settings button to save the changes, or
click the Cancel Changes button to undo your changes. Help information is shown on the right-hand side of a
screen. For additional information, click More.
