System Log − Intruder Blacklist

The DFL-100’s firewall is pre-programmed to recognize and block many

commonly used intrusion methods from computers on the WAN (Internet,)

from one computer to another on the LAN, and from computers on your LAN

to the WAN. In addition, you can define a Port Filter Policy, that will set

additional intrusion criteria for the DFL-100’s firewall to block connections.

When a serious intrusion attempt is detected (that is, when a large number of

packets consistent with a commonly used intrusion method are detected by

the DFL-100) the IP address, the protocol used, and the corresponding port

number is determined and entered into the DFL-100’s Intruder Blacklist.

Once the intruder’s information is entered, the DFL-100’s firewall will block

packets from this location from crossing the DFL-100 (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-100’s Intruder

Blacklist, that IP address is blocked from sending packets through the DFL-

100.

You can clear the Intruder Blacklist at any time by clicking the Clear button.
