You can disable a security rule, that is, remove it from the list of rules that are used for scanning. You can do this only with custom rules.
To enable or disable a rule:
In the main menu of the Open Single Management Platform Console, go to the Application & Services → NGFW section.
This opens the Policy tab.
In the Firewall section, select Security rules.
In the table of rules, do one of the following:
Set the toggle switch in the Status column next to the relevant rule to On or Off.
Click the name of the rule to open a window and in that window, in the General section, set the Status toggle switch to On or Off.
Select the check box next to the relevant rule and click Edit. In the displayed window, in the General section, set the Status toggle switch to On or Off.
If you have disabled a rule, but there are active sessions that match the newly disabled security rule, such sessions are not terminated.
