Windows Firewall
Fritzi Schlicker
To turn it off, switch the setting to Off. Turning off Microsoft Defender Firewall could make your device (and network, if you have one) more vulnerable to unauthorized access. If there's an app you need to use that's being blocked, you can allow it through the firewall, instead of turning the firewall off.
This type of rule is often combined with a program or service rule. If you combine the rule types, you get a firewall rule that limits traffic to a specified port and allows the traffic only when the specified program is running. The specified program cannot receive network traffic on other ports, and other programs cannot receive network traffic on the specified port. If you choose to do this, follow the steps in the Create an Inbound Program or Service Rule procedure in addition to the steps in this procedure to create a single rule that filters network traffic using both program and port criteria.

In the preceding command, the value of can be UNRESTRICTED or RESTRICTED. Although the command also permits the value of NONE, that setting means the service cannot be used in a firewall rule as described here. By default, most services in Windows are configured as UNRESTRICTED. If you change the SID type to RESTRICTED, the service might fail to start. We recommend that you change the SID type only on services that you want to use in firewall rules, and that you change the SID type to UNRESTRICTED.
It is a best practice to restrict the firewall rule for the program to only the ports it needs to operate. On the Protocols and Ports page, you can specify the port numbers for the allowed traffic. If the program tries to listen on a port different from the one specified here, it is blocked. For more information about protocol and port options, see Create an Inbound Port Rule. After you have configured the protocol and port options, select Next
By default, Windows Defender Firewall allows all outbound network traffic unless it matches a rule that prohibits the traffic. This type of rule prevents the program from sending any outbound network traffic on any port. To create an outbound firewall rule for a program or service:
Allow an app through firewall - If the firewall is blocking an app you really need, you can add an exception for that app, or open a specific port. Learn more about that process (and why you might not want to) at Risks of allowing apps through Microsoft Defender Firewall.
Advanced settings - If you're knowledgeable about firewall settings this will open the classic Windows Defender Firewall tool which lets you create inbound or outbound rules, connection security rules, and see monitoring logs for the firewall. Most users won't want to dig into it that deeply; adding, changing, or deleting rules incorrectly can cause your system to be more vulnerable or can cause some apps not to work.
Restore firewalls to default - If someone, or something, has made changes to your Windows Firewall settings that is causing things not to work properly you're just two clicks away from resetting the settings back to the way they were when you first got the computer. If your organization has applied any policies to configure the firewall those will be reapplied.
I have a system (Army Gold Master 7, using TestStand and CVI) that has "standard" government firewall rules. We are trying to communicate over Ethernet to specialized devices and we see no traffic unless we disable the firewall. We are not on the internet (not allowed by gov). The specialized devices send out a broadcast for request for IP but the software never sees it.
When you disable the firewall and are able to communicate with the device, how does the device receive its IP address? For example, is it automatically assigned one by Windows or your router (with DHCP) or does it have a static IP assigned to it? It's possible that the IP is getting assigned, but since the specific communication port is blocked by the firewall, communication cannot occur.
I try to pair it with my EOS M10 in windows 10 but it always come up with error :''WFT Firewall Settings has stopped working'', May i know how you did with the language settings ? did you mean the OS language setting ?
But then I had an idea, Crap! Is this another Windows Firewall problem on the server? I turned off the server's firewall private and public profile temporarily, and the client PC hooked up right away with :6080/arcgis/services.
I don't know why the first two in your link should work. I'm not sure why you would think it is not a firewall issue. I'm talking about the SampleWorldCities map service that appears by default after installing Server. The service seems to be using the defaults. There are no authentications set on the service, https/ssi are not involved. Simply adding the service in ArcCatalog as user or administrator with :6080/arcgis works fine when I remote desktop to the server. On a client machine, Add ArcGIS Server doesn't work for any of the urls I tried, but it connects easily if I turn off Windows Firewall on the server temporarily. Shouldn't I concentrate on making a firewall exception for port 6080?Already this week I had to work on the firewall to get license service through the firewall.
Now, can I (should I) somehow copy the windows Hosts file to PFSense and just kill Windows Firewall? (hosts file being the file the Firewall uses to block access to certain IPs/domains) - I was wrong, as Dexter_Kane pointed out, the hosts file is a DNS thing not a Firewall thing.
Same rule still applies though, unless you have a good reason to turn it off, keep the firewall on. Start straying from good practice and you end up forgetting you did it and mess up sometime down the line.
GlassWire would have that live stalking without much usage, but havent used it as firewall myself, just as this stalking thing like why is my Win10 sending few byte zigzags around globe to company servers
I'm trying to configure Windows firewall with Advanced Security to log and tell me when programs are trying to make outbound requests. I previously tried installing ZoneAlarm, which worked wonders for me with this in Windows XP. But now, I'm unable to install ZoneAlarm on Windows 7.
Update
I've enabled all the logging options available through the properties windows of the Windows Firewall with Advanced Security Console. But I'm only seeing logs in the %systemroot%\system32\LogFiles\Firewall\pfirewall.log file, not in the Event Viewer, as the first answer suggested.
I stopped/restarted the universal forwarder service but yet I am not getting the firewall logs yet, even after generating new traffic. I search for sourcetype=winfw and I get no results. I suspect that I'm missing something rather simple but I can't seem to figure it out.
I already tested Windows firewall advanced settings under properties and checked block all for inbound/outbound in domain/private/public, and didn't encounter problems with internet connection or loading Firefox. But I still got hacked and subsequently reinstalled O/S following that -- without the certainty that my system is 100% clean of malware. I would have wished Malwarebytes would offer endpoint monitoring as they do for businesses.
Adding to that, if I were to change the pre-made firewall rules added during installation to only work on private networks (such as the zerotier x64 binary rule), would this still allow my connections to work?
What's weird is it only happens once. If the user clicks Cancel, we close the session, and the user starts a new connection there's no prompt that time. Even weirder is that since it's a cancel, I'm not finding any LogMeIn related firewall permissions created as a result of this, so I'm back to wondering what entries should be created ahead of time.
It is deployed with a standard MSI. I just wrap the MSI into a .InTuneWin package for distribution, it should be running the MSI on the target machine same as if it was downloaded there. Is there something in the calling card configuration that I missed that would set up the firewall?
Or what's more likely is that it's running the MSI out of the administrator login, not out of the user login elevated, and the installer's firewall rules only apply to the current user. If I was to put calling card on a machine direct with the MSI and admin permission, would the firewall problem repeat for a newly created local user account?
As for on-network? I wouldn't say if it's the end of the world if you got a good defense-in-depth strategy otherwise (network level firewalls, IDS, antivirus, etc). But at the same time, if something gets loose on the network and tries to spread, having a good host-based firewall can help mitigate the spread.
We have had a number of issues with lazy engineers turning firewalls off because it was hard. Most don't work here any more and we are turning them back on as we find them. It is easy enough to use something like cports to gather data about what ports are in use, then apply to the test environment, then apply to prod
This is extremely bad practice. It is sad when people decide to take the lazy route of disabling the firewall on internal servers. It is completely bizarre that you would disabled something that protects your server. There is absolutely no good reason for disabling the firewall permanently. Doing it temporarily for testing is fine.
