Chapter 5: Configuring the Router

The Security Tab - Firewall

Broadband Router with 2 Phone Ports

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 and block anonymous

Internet requests.

Firewall

The firewall uses Stateful Packet Inspection (SPI) to check the incoming data transmissions before allowing them

to enter your network. To enhance the security of your network, this feature is enabled by default and cannot be

disabled.

Additional Filters

Filter Proxy. Use of WAN proxy servers may compromise the Router’s security. If you deny proxy, you will block

access to any WAN proxy servers. Click the checkbox to enable proxy filtering.

Filter Cookies. A cookie is data stored on your PC and used by Internet sites when you interact with them. Click

the checkbox to enable cookie filtering.

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. Click the checkbox to enable Java

Applet filtering.

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. Click the checkbox to enable ActiveX

filtering.

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. Click the checkbox to enable multicast filtering.

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. Click the checkbox to block anonymous Internet requests. This feature is enabled by default.

When you have finished making changes to this screen, click the Save Settings button to save the changes, or

click the Cancel Changes button to undo your changes. For help information, click Help.
