D-Link DFL-600 Manual page 70

Once the intruder's information is entered, the DFL-600's firewall will block
packets from this location from crossing the DFL-600 (from the WAN to the
LAN, from two computers on the LAN, or from the LAN to the WAN).
Once an intruder's IP address is listed in the Intruder Blacklist, it will remain
until it times out. Each new intrusion attempt will reset the timer, and the
intruder's IP address will remain in the Intruder Blacklist for an additional
amount of time. While the intruder's IP address is on the DFL-600's Intruder
Blacklist, that IP address is blocked from sending packets through the DFL-
600.
