packets from the attack source IP according to the time setting. After the blocking time,
the SG-500 will re calculate the total ICMP flow from every source IP, if over the setting
value, then SG-500 will keep blocking.

‹ UDP Flood Threshold (Per Source IP )： Define every source IP and the total UDP
packets（Pkts/Sec） pass through the SG-500. If over the setting value, then SG-500 will
define it to be attacked.
‹ UDP Flood Threshold Blocking Time ( Per Source IP )： The SG-500 will block the
packets from the attack source IP according to the time setting. After the blocking time,
