The Security Tab - Firewall

The Firewall screen offers a firewall and filters that block specific Internet data types.

Firewall

Firewall Protection. A firewall enhances network security and uses Stateful Packet Inspection (SPI) for more detailed review of data packets entering your network. Select Enabled to use a firewall, or Disabled to disable it.

Internet Filter

Filter Anonymous Internet Requests. When enabled, this feature keeps your network from being “pinged,” or detected, by other Internet users. It also hides your network ports. Both make it more difficult for outside users to enter your network. This filter is enabled by default. Select Disabled to allow anonymous Internet requests.

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.

Filter Internet NAT Redirection. This feature uses port forwarding to block access to local servers from local networked computers. Select Enabled to filter Internet NAT redirection, or Disabled to disable this feature.

Filter IDENT (Port 113). This feature keeps port 113 from being scanned by devices outside of your local network. Select Enabled to filter port 113, or Disabled to disable this feature.

Web Filter

Proxy. Use of WAN proxy servers may compromise the Gateway's security. Denying Filter Proxy will disable access to any WAN proxy servers. To enable proxy filtering, click the checkbox.

Java. Java is a programming language for websites. If you deny Java, you run the risk of not having access to Internet sites created using this programming language. To enable Java filtering, click the checkbox.

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 the checkbox.

Cookies. A cookie is data stored on your computer and used by Internet sites when you interact with them. To enable cookie filtering, click the checkbox.

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 more information, click Help.
