PowerShell dolazi s Netsecurity modulom koji vam omogućuje da konfigurirate Windows vatrozid^{( configure the Windows Firewall)} . Možete koristiti funkciju — New-NetFirewallRule — u Netsecurity za blokiranje IP-a ili web-mjesta pomoću PowerShell - a u sustavu Windows^(Windows) . Značajka vam omogućuje stvaranje novog ulaznog ili izlaznog pravila vatrozida i dodaje pravilo ciljnom računalu.

Blokirajte IP^{(Block IP)} ili web^(Website) -mjesto pomoću PowerShell-a^(PowerShell)

Dok blokiranje raspona IP-a funkcionira savršeno, blokiranje web stranice ili domene je nezgodno. To je zato što na domenu može biti priključeno više IP-ova, a iako ih možete spriječiti, DNS razrješavač može otkriti drugi IP svaki put kada postavi upit. Također, s vremena na vrijeme, isti IP mogu koristiti povezane usluge, a blokiranje tog IP-a značilo bi blokiranje i drugih usluga.

1. Blokirajte^(Block) lokalne ili internetske IP adrese
2. Blokirajte nazive web-mjesta ili domena

Trebat će vam administratorske privilegije da ih izvršite.

1] Blokirajte IP^{(Block IP)} ili raspon^(Range) pomoću PowerShell -a^(PowerShell)

Koristeći ovu naredbu, možete koristiti jednu IP adresu ili raspon IP adresa. Izvršite sljedeću naredbu u PowerShell-u.^{(PowerShell.)}

New-NetFirewallRule -DisplayName "Block XYZ.com IP address" -Direction Outbound –LocalPort Any -Protocol TCP -Action Block -RemoteAddress 146.185.220.0/23

IP adresu Block XYZ.com^{(Block XYZ.com IP)} možete zamijeniti bilo čime što se možete sjetiti ili olakšava razumijevanje kad god se osvrnete na nju. IP adresa spomenuta na kraju opcije RemoteAddress je ono što će biti blokirano. Svaka web-lokacija ili usluga koja to riješi bit će blokirana. Opciju RemoteAddress^{(LocalAddress)} možete zamijeniti opcijom LocalAddress^{(RemoteAddress)} ako je IP IP adresa lokalne mreže.

Nakon što je izvršenje dovršeno, trebali biste primiti statusnu poruku kao "Pravilo je uspješno raščlanjeno iz trgovine. (65536)”. Otvorite Windows vatrozid^{(Windows Firewall)} i provjerite je li unos dostupan. Nakon potvrde, trebali biste moći dodati još pomoću PowerShell -a .

2] Blokirajte web^{(Block Website)} -mjesto ili domenu^(Domain) pomoću PowerShell -a^(PowerShell)

Budući da funkcija ne podržava blokiranje URL -a , imamo dva izbora. Prvo^(First) je upitati sve moguće IP adrese te domene i blokirati ih. Drugi je pronaći poznate službene IP raspone i blokirati ih. Potonji ima manje šanse da slučajno blokira druge usluge u usporedbi s prvim. Uz to, ako je blokiranje domene neophodno, uvijek možete upotrijebiti drugi softver da ih blokirate.

Resolve-DnsName "facebook.com"

Zabilježite IP adresu koju ćemo koristiti u drugoj metodi

New-NetFirewallRule -DisplayName "Block XYZ.com IP address" -Direction Outbound –LocalPort Any -Protocol TCP -Action Block -RemoteAddress 146.185.220.0/23

Kada sam ovo koristio s YouTubeom^(YouTube) , nije radilo iako je izravni IP bio blokiran. Kad sam ga koristio s Facebookom^(Facebook) , radio je. Dakle, ako se web stranica može riješiti korištenjem više IP adresa, ova metoda neće raditi.

Korištenje PowerShell naredbi je jednostavno. Ako ste ikada koristili naredbeni redak, jednako je dobar; Nadam se da ste uspjeli uspješno blokirati IP ili web stranicu pomoću PowerShell - a u sustavu Windows^(Windows) . Kad^(Anytime) god ih želite ukloniti, to možete učiniti iz vatrozida sustava Windows^{(Windows Firewall)} ili upotrijebiti naredbu Remove-NetFirewallRule  .

How to Block IP or a Website using PowerShell in Windows 10

PowerShell comes with a Netsecurity module that allows you to configure the Windows Firewall. You can use the function — New-NetFirewallRule — in Netsecurity to block an IP or a website using PowerShell in Windows. The feature allows you to create a new inbound or outbound firewall rule and adds the rule to the target computer.

Block IP or Website using PowerShell

While blocking IP ranges work perfectly, blocking a website or domain is tricky. That’s because there can be a multiple IP attached to the domain, and while you can prevent them, the DNS resolver can figure out a different IP every time it queries. Also, at times, the same IP could be used by related services, and blocking that IP would mean blocking other services as well.

1. Block local or internet IP addresses
2. Block website or domain names

You will need admin privileges to execute these.

1] Block IP or Range using PowerShell

Using this command, you can use a single IP address or range of IP addresses.  Execute the following command in PowerShell.

New-NetFirewallRule -DisplayName "Block XYZ.com IP address" -Direction Outbound –LocalPort Any -Protocol TCP -Action Block -RemoteAddress 146.185.220.0/23

You can replace Block XYZ.com IP address with anything you can remember or makes it easy to understand whenever you look back at it. The IP address mentioned at the end of the RemoteAddress option is what will be blocked. Any website or service that resolves to that will be blocked. You can replace the RemoteAddress option with the LocalAddress option if the IP is the local network IP address.

Once the execution is complete, you should receive a status message as ” The rule was parsed successfully from the store. (65536)”.  Open Windows Firewall and check if the entry is available. Once confirmed, you should be able to add more using PowerShell.

2] Block Website or Domain using PowerShell

Since the function doesn’t support URL blocking, we have two choices. First is to query all possible IP of that domain, and block them. The second is to find known official IP ranges and block them. The later has lower chances of accidentally blocking other services compared to the former. That said, if blocking a domain is essential, you can always use another software to block them.

Resolve-DnsName "facebook.com"

Note the IP address which we will use in the second method

New-NetFirewallRule -DisplayName "Block XYZ.com IP address" -Direction Outbound –LocalPort Any -Protocol TCP -Action Block -RemoteAddress 146.185.220.0/23

When I used this with YouTube, it did not work though direct IP was blocked. When I used it with Facebook, it worked. So if a website can be resolved using multiple IP addresses, then this method will not work.

Using PowerShell commands are straightforward. If you ever used the command prompt, it is as good as that; I hope you were able to block IP or a website using PowerShell in Windows successfully. Anytime you want to remove them, you can do so from Windows Firewall or use the Remove-NetFirewallRule command.
