¾Enable ICMP-FLOOD Attack Filtering - Enable or Disable the ICMP-FLOOD Attack Filtering.
¾ICMP-FLOOD Packets threshold: (5 ~ 3600) - The default value is 50. Enter a value between 5 ~ 3600 packets. When the current ICMP-FLOOD Packets numbers is beyond the set value, the router will start up the blocking function immediately.
¾Enable UDP-FLOOD Filtering - Enable or Disable the UDP-FLOOD Filtering.
¾UDP-FLOOD Packets threshold: (5 ~ 3600) - The default value is 50. Enter a value between 5 ~ 3600 packets. When the current UPD-FLOOD Packets numbers is beyond the set value, the router will start up the blocking function immediately.
¾Enable TCP-SYN-FLOOD Attack Filtering - Enable or Disable the TCP-SYN- FLOOD Attack Filtering.
¾TCP-SYN-FLOOD Packets threshold: (5 ~ 3600) - The default value is 50. Enter a value between 5 ~ 3600 packets. When the current TCP-SYN-FLOOD Packets numbers is beyond the set value, the router will start up the blocking function immediately.
