Method 3. Check for blocked programs before trying this method. Changing your firewall's port behavior is a bit technical, and a mistake here can cause issues with security or function. If you haven't tried it yet, start with the much easier test for blocked applications. You won't need an IT degree or anything, but this method could be tricky if you're not used to troubleshooting network issues.
It gets a lot easier if you already have some idea of the problem. For instance, you could check the customer support forums for the app you are having trouble with, and look for known firewall issues with specific ports.
Open the Windows Firewall. Select "Advanced Settings" on the left menu. Click Properties. This is located underneath the "Actions" header in the right-hand panel, or in the top Actions menu. Select the tab that matches your network. Windows Firewall uses different settings for different networks. In the top row of tabs, select "Private Profile" if you're on a home network or "Public Profile" if you're on public WiFi.
The "Domain Profile" is for secure networks with a domain controller, mostly in corporate settings. Customize your logging settings. Under the "Logging" heading, click Customize. In the window that opens, select the drop-down menu next to "Log dropped packets" and set it to "Yes". Make a note of the file path at the top, next to "Name". Hit "OK" twice to close the windows and save your settings. Test the application that's having issues.
Run the application or feature that you think might be running into your firewall. This should record the attempt in your firewall log so you can see what's going on. You might need to close and reopen the log between tests to see the latest info. Open the firewall log. To see your firewall activity, go to the file path location shown in your logging settings.
Look for port info in the log. Use the Fields line at the top as a guide for how to read the log entries for example, the Fields line starts with "date time", so the first two items in each entry are the date and time of the event.
Fortunately, you can ignore most of this info and look for the following: [24] X Research source "Action" lists the firewall's behavior. Your firewall needs to know which of these protocols is being used to govern data transmission.
Make a note of this. You can also search for info on that port online, since some ports are associated with certain common uses. Use this info to edit your firewall rules. Return to the advanced settings window for your firewall. Use the actions in the left pane to create a new rule: [26] X Research source Click "Outbound Rules" to alter how your programs are allowed to connect to the network.
This is the info you got from your log. Choose "Allow", "Allow if it is secure", or "Block", depending on what you'd like your firewall to do. Choose the Profile type s of the networks you want the rule to apply to. Name your rule and save it. Check whether the new rule worked.
Repeat the action that you've been having problems with for instance, opening an application, running a program, or visiting a website. If it now works as intended, you're done. If not, open the log again and double-check that you've used all the right info, and that there are no other issues being recorded such as additional undesired blocks on other ports. Turn off logging once you're done troubleshooting. Return to the Windows Firewall advanced settings.
Select the profile tab you changed before, click Customize under Logging, and turn off dropped packet logging. This will help prevent slowdowns that can happen from constant logging. Method 4. Go to the Security settings in System Preferences.
Click the Apple icon in the top left corner of your screen, and choose System Preferences. Select the Firewall tab. If you see "Firewall: Off", which is the default setting for Apple computers, then this firewall isn't blocking anything though there are still other protections built in to the operating system. If it is on, keep reading to get into the specifics.
