Network Protection Firewall Violations - Where am I going wrong and how to fix

Budgie2

Still at lowest end of learning curve and have found that I am getting 80+ firewall violations reported daily and 0 prevention statistics.

I am very concerned that I have something wrong with my protection and seek help in identifying where to look and how to fix please.

Budge.

    I don't really understand what you are asking about/concerned about.  Are you seeing IPS violations, dropped destination/source hosts and thinking this is an issue?  Is it web traffic being blocked/reported?  

    Can you copy/paste the log in which you are referring, and/or click and drag a screenshot into the reply window so we can see what you are specifically referring to?

    Firewall-violations are ok.

    Here are all packets counted, you don't allow passing the firewall.

    Even if you use an "any - any - any" rule you will see/count dropped packets. These may be broadcasts or packets directed to interface-IP of the firewall.

    if your services are available .. without problems ... you can ignore the dropped packets / Firewall-violations (we have multiple hundred per minute at the company)

    You can open the firewall-live-log and take a look to the allowed/dropped packets. You may post these logs if there are questions.

    PS: IPS-violations = 0  is good too.
