Wireless-N Gigabit Gaming Router

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 Enable to use a firewall, or Disable to disable it.

Block WAN Request

Block WAN 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. Click in the box to block anonymous internet requests.

When you have finished making changes to this screen, click SAVE SETTINGS to save the changes, or click CANCEL CHANGES to clear all fields and start over.
