TCP/UDP Port Scan: To detect any suspected port scan behavior within the packet flow.
TCP Null Scan: When checking the flags of TCP header without any setting, the router determines this situation as TCP Null Scan and drops this packet.
TCP X’mas Tree Scan: When checking the flags settings of TCP header do not comply with the rule of RFC793, the router will determines this situation as TCP X’mas Tree scan and drops this packet.
TCP Full X’mas Tree Scan: When checking the flags settings of TCP header have been configured, the router determines this situation as TCP Full X’mas Tree Scan and drops this packet.
SYN Flood: To block the suspected SYN Flood attacked.
SYN Limit Rate: When enable SYN Flood function, you can enter the limit rate for TCP SYN packets which allow to pass per second.
FIN Flood: To block the suspected FIN Flood attacked.
FIN Limit Rate: When enable FIN Flood function, you can enter the limit rate for TCP FIN packets which allow to pass per second.
UDP Flood: To block the suspected UDP Flood attacked.
UDP Limit Rate: When enable UDP Flood function, you can enter the limit rate for TCP UDP packets which allow to pass per second.

Port Trigger Setting: Enable/Disable the port trigger.
Trigger Port: This is the port used to trigger the application. It can be either a single port or a range of ports.
Trigger Protocol: This is the protocol used to trigger the special application.
Public Port Range: This is the port number on the WAN side that will be used to access the application. You may define a single port or a range of ports. You can use a comma to add multiple ports or port ranges.
