How to Check What Ports My VPN Blocks

If you’re looking for a way to unblock ports on your VPN, you’ve come to the right place. We’re going to show you the best way to do this, as well as the ports that most VPNs block. Keep reading for more information.

Check Out What Ports My VPN Blocks

The best way to find out which ports your VPN blocks is to enter the command “sudo nmap –sP (your VPN’s IP address)” into a terminal window (command line), where (your VPN’s IP address) is the IP address of your VPN. After entering this command, you’ll begin to see a list of the ports that your VPN blocks. These are the ports that you need to unblock to use Tor and other apps that utilize the services of the Tor network.

For instance, let’s say that you have a VPN with the IP address of 119.29.195.147 – if you type 119.29.195.147 into a terminal window and enter the command “sudo nmap –sP”, you’ll see that port 80 is blocked. This is the standard HTTP port that websites use to contact your device – if your VPN blocks this port, you won’t be able to access websites that use port 80, such as Google and Facebook.

To be able to access these websites, you’ll need to unblock port 80 on your device. You can do this by entering the command “sudo nmap –p80 (your VPN’s IP address)” into a terminal window (command line), where (your VPN’s IP address) is the IP address of your VPN. After you enter this command, you’ll see a list of the ports that your VPN allows you to access.

Ports That Most VPNs Block

Based on our own experiences and the feedback we’ve gotten from users, here’s a list of the ports that most VPNs block:

  • 22
  • 25
  • 53
  • 80
  • 110
  • 143
  • 443
  • 591
  • 993

If you’re looking to access websites that are blocked in your country, chances are you’ll be looking to unblock one (or more) of these ports, so that you can access your desired websites. Of course, you’ll need to ensure that your VPN works in your country, and that you’re not leaving a country that suppresses free speech – but you can read more about that here.

Unblock Ports On Your VPN

If you block a port on your device using a VPN, and you connect to that same VPN when planning on accessing a website or app that uses that blocked port, you’ll end up with your device in a network called a “split tunnel”. A network in which some devices are blocked and others aren’t. As a result of connecting to this split tunnel network, you’ll have limited access to the resources (websites, servers, etc.) that it provides. Not exactly what you want, is it?

To avoid this issue, you must ensure that all of your devices are always connected to the same VPN. This way, your device will always be able to access the resources it needs – regardless of whether or not that device is connected to the internet.

To unblock ports on your VPN, you must first disconnect from your VPN. Then, you can enter the specific port that you want to unblock into a terminal window (command line), whereupon the device will ask you for the password that you use to connect to the VPN. Once you enter this password, the device will unblock the specified port.

Why Are Ports Usually Blocked?

Ports are usually blocked to prevent users from accessing resources that are not created for human consumption. For example, devices connected to a VPN will not be able to access resources on a server that provides pornographic content – not even if you change the configuration of your device to unblock all ports. Even if you don’t want to access pornographic content, you might accidentally end up accessing something else that your device is not configured to access. This is why most ports are blocked by default – so that users do not have access to resources that they are not supposed to see.

How To Check For Updates

If you want to stay up-to-date with the latest security patches and other software updates, you can enter the command “sudo apt update” followed by the command “sudo apt upgrade” into a terminal window (command line), where (your VPN’s IP address) is the IP address of your VPN. After updating your device, you’ll be able to access the internet with all of the resources that your device needs, without any obstacles (ports, etc.) stemming from a VPN.

Use A Secure Password For Your VPN

No matter what kind of protection you choose- VPN, password, PIN, etc.- it’s crucial that you use a secure password for your VPN. This is because, as stated above, ports are usually blocked by default on most devices to prevent users from accessing resources that are not supposed to be accessed by humans. If you use a weak password for your VPN, it won’t be long before anyone can guess it and gain access to your personal data. Once they’ve got access to your personal data (which, in most cases, is all of your sensitive information), it’s basically game over. You won’t be able to login to your device, and there’s a good chance that your data will be compromised.

To secure your VPN, you must use a strong password that is unique to you. Fortunately, creating a strong password is not as difficult as you might think. Simply follow these steps to create a strong password:

  • Choose a password that is at least eight characters long.
  • Do not use any dictionary words or phrases in your password.
  • Do not use any of the words in the dictionary
  • Use numbers, lowercase letters, and uppercase letters.
  • Do not use the same word twice in a row
  • Do not use any of your current passwords as your new password
  • Do not use any common passwords
  • Once you’ve created your secure password, write it down and keep it somewhere safe. This way, you’ll never forget it.
