How to configure ADP block IP time period?
Zyxel Employee
Background and Scenario:
Could it be possible to limit the tries from a certain IP to a port forward on the USG FLEX series? For example, someone that sends a DOS to an opened port, if he tries 5 times in a short amount of time, that is blocked for 1 hour.
Answer:
You could configure the block period to 3600 seconds on the ADP profile, as below:
Therefore, if the firewall detects there are ADP events, and will block the suspicious source IP.
Please refer to the below description of Block Period: "Specify for how many seconds the Zyxel Device blocks all packets from being sent to the victim (destination) of a detected anomaly attack. Flood Detection applies blocking to the destination IP address and Scan Detection applies blocking to the source IP address."
