In the open box, enter in a URL (i.e., www.dlink.com) or an IP
address and click on Ping to test your internet connection.
Click Reboot to restart the unit.
Click Enable to block the WAN ping. Computers on the Internet
will not get a reply back from the DI-824VUP+ when it is being
"ping"ed. This may help to increase security.
When this feature is enabled, the router will record the packet
information passed through the router such as IP address, port
address, ACK, SEQ number, and so on. The router will also check
every incoming packet to detect if it is valid.
When DoS is enabled, the router will prevent Denial of Service
attacks on all computers connected to the DI-824VUP+.
