The Security Tab - Firewall

Block WAN Requests. Enable the Block WAN Request feature by checking the box beside Block Anonymous Internet Requests and you can prevent your network from being “pinged,” or detected, by other Internet users. The Block WAN Request feature also reinforces your network security by hiding your network ports. Both functions of the Block WAN Request feature make it more difficult for outside users to work their way into your network. This feature is enabled by default.
