To set rules based on the incoming activity analyzed for the Rule Wizard, open the Plan Incoming IP Security screen, as shown in Analyzing Recent Data on Incoming Activity by IP Address with the Rule Wizard (STRFW > 2 > 42).

In this case, the only activity from IP address 1.1.1.77 requested access to the file server. Therefore, the new rule would allow access to the file server and block access to all the others.

To set new rules corresponding to how activity differed from the existing rules, enter 3 in the Opt field for that address.

Since the only difference between the existing rules and the actual activity for IP address 1.1.1.77 was that access was requested for the file server, which would previously have been rejected, the setting for that server would be changed from N to Y.

To save changes and exit this window, press Enter. The Rules Wizard saves the rule being changed and removes the line for that IP Address from the screen. You can see the resulting rule on the Dynamic Filtering- Incoming IP Address Security screen, as shown in Setting Firewall Rules for Incoming Activity by IP Addresses (STRFW>2 > 1).

To exit this window without saving changes, press the F12 key. The window closes. The changes that would have been made are marked in the columns for those servers in the lines for those IP addresses on the screen. You can then further work with the rules and save them manually, as shown in Analyzing Recent Data on Incoming Activity by IP Address with the Rule Wizard.
