If normal service traffic is intercepted, perform either of the following operations:

Query the ID of the rule that blocks traffic and modify the action of the rule in the IPS rule library. For details, see Querying Hit Rules and Modifying Protection Actions.
Use a less strict IPS protection mode. For details, see Configuring Intrusion Prevention.

Log in to the management console.
Click in the upper left corner of the management console and select a region or project.
In the navigation pane on the left, click and choose Security & Compliance > Cloud Firewall. The Dashboard page will be displayed.
(Optional) If the current account has only one firewall instance, the firewall details page is displayed. If there are multiple firewall instances, click View in the Operation column of a firewall to go to its details page.
In the navigation pane, choose Log Audit > Log Query. Click the Attack Event Logs query and record the Rule ID of the rule that blocks traffic.

In the navigation pane, choose Attack Defense > Intrusion Prevention. Click View Effective Rules under Basic Protection. The Basic Protection tab is displayed.
Search for the rule by its ID. In the Operation column, change its action to Observe or Disable.
- Observe: The firewall logs the traffic that matches the current rule and does not block the traffic.
- Disable: The firewall does not log or block the traffic that matches the current rule.
