How to allow Google to crawl my Site, when DOS Profile is active?

So I opened a ticket for this topic and get this as solution from F5: 1) For this feature to be fully functional F5 recommend to configure a DNS resolver 2) We will recommend to configure a forward zone with "." in FQDN name 3) Also we will recommend to configure the DoS profile on "Bot Signatures", with "Report" enabled for the "Search Bot" and "Search Engine" categories. Remove the Bot Signature List since this overrides the configured actions for the bot signature categories. 4) To validate/verify if this change solves the issue, You can use the google tool to test your website https://support.google.com/webmasters/answer/6065812?hl=en

Now everything is working. Hope this answer will also help others with similar issues
