Never bothered to log connections - don't see the point. Don't know what the free versions are like now though. They still have a free version, but its features compare to "Plus" version are worthless.

For example, common settings for Domain Profile could be that the firewall is turned off. This is the case because administrators manage our Firewall from central location.
However, in Private and Public profiles we want to have our Firewall turned on. In the Custom Settings windows we can set how notifications are displayed, or how to respond to multicast or broadcast network traffic. Also, we can select how to merge local rules and rules set trough Group Policy. Logging is great for troubleshooting.
We can change the default size limit of the file, and what to do with dropped packets and successful connections. In the fourth tab we can see IPsec Settings. When we go back to the Overview window we can see that the Firewall is turned off for Domain Profile.
We assume that we have some kind of enterprise firewall protecting our whole network in this case. On the left-hand size we select to customize our Inbound and Outbound rules. By default, all externally initiated traffic is blocked unless we have made an inbound rule exception. In contrast, outbound rules are wide opened by default which means that any traffic is allowed out.
Now, notice that each rule in Inbound Rules are several times in the list. We can see if it is enabled or not and short description. On the General tab in the Action section we see IPsec related configuration. Also, important tab is Users and Computers.
This is where we can configure which computers and users are allowed to use this rule. On the Protocols and Ports tab we can see which protocols and which port this rule applies to. On the Scope tab we can set which IP addresses are allowed to use that particular service.
On the Advanced tab we can select to which profiles and which interfaces does this rule apply to. New Inbound Rule Wizard will open. In the first step we have to select what type of rule we want to create.
Our rule can control a program, port, some predefined connections or we can create custom rule. In our case we will select Port and click Next. We will just enter some example port, choose TCP and click Next. On the next screen we set what to do if the traffic meets specified conditions.
In our case we will block the connection and click Next. On the next screen we select which profiles does this rule apply to. We will select all profiles and click Next. On the next screen we can name our rule and give it short description. In our case we named it Example Block Rule. After that we can click Finish. Notice that in the rule list, our rule has little red icon, which means that it will block the traffic that meets this rule. Disabled rules are grayed out.
Firewall settings change based on the network location type. For each network profile we can set customized settings. We can import and export all our Firewall settings. Rules with red icon are blocking rules.
Green icons represent rules which allow traffic. This site uses Akismet to reduce spam. Learn how your comment data is processed. In the process of filtering Internet traffic, all firewalls have some type of logging feature that documents how the firewall handled various types of traffic. These logs can provide valuable information like source and destination IP addresses, port numbers, and protocols.
By default, the log file is disabled, which means that no information is written to the log file. A new dialog box appears. A new window opens and from that screen choose your maximum log size, location, and whether to log only dropped packets, successful connection or both.
A dropped packet is a packet that Windows Firewall has blocked. In most production environments, this log will constantly write to your hard disk, and if you change the size limit of the log file to log activity over a long period of time then it may cause a performance impact. The log file will be created in a W3C extended log format. A single log file can contain thousands of text entries, so if you are reading them through Notepad then disable word wrapping to preserve the column formatting.
If you are viewing the log file in a spreadsheet then all the fields will be logically displayed in columns for easier analysis. The Windows Firewall security log contains two sections. The header provides static, descriptive information about the version of the log, and the fields available.
The body of the log is the compiled data that is entered as a result of traffic that tries to cross the firewall. It is a dynamic list, and new entries keep appearing at the bottom of the log. The fields are written from left to right across the page. The - is used when there is no entry available for the field. According to the Microsoft Technet documentation the header of the log file contains:.
Version — Displays which version of the Windows Firewall security log is installed. Software — Displays the name of the software creating the log. Time — Indicates that all the timestamp information in the log are in local time. Fields — Displays a list of fields that are available for security log entries, if data is available.
The hours are referenced in hour format. As you notice, the log entry is indeed big and may have up to 17 pieces of information associated with each event.
However, only the first eight pieces of information are important for general analysis. With the details in your hand now you can analyze the information for malicious activity or debug application failures. If you suspect any malicious activity, then open the log file in Notepad and filter all the log entries with DROP in the action field and note whether the destination IP address ends with a number other than If you find many such entries, then take a note of the destination IP addresses of the packets.
Once you have finished troubleshooting the problem, you can disable the firewall logging.
