The Security Tab - Firewall
When you click the Security tab, you will see the Firewall screen. The Router’s firewall enhances the security of your network. You can also enable a variety of filters to further protect your network.
Firewall
Firewall Protection. The firewall uses Stateful Packet Inspection (SPI) to check the incoming data transmissions before allowing them to enter your network. To use the Router’s firewall, click Enabled. If you do not want firewall protection, click Disabled.
Additional Filters
Filter 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.
Filter 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.
Filter Java Applets. 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.
Filter 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.
Filter 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.
Block WAN Requests
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.
