When your computer’s connected to the internet without a firewall, it’s like you’re leaving your front door wide open—anyone can walk right in. Think of your firewall as “Jeeves”, a steadfast doorman who decides who’s allowed in and who’s not. But sometimes Jeeves oversteps his bounds and denies someone entry. You need to give him an updated list of preferred guests so he doesn’t turn away those who are invited. In this guide, we’ll teach you how to allow Minecraft through your firewall, as well as other apps like Spotify, Roblox, and other games or apps.
Why does my firewall block games and apps? Playing games online can be risky. From predators who lurk on servers with kids’ games to hackers trying to overload servers with DDoS attacks. It’s no wonder your firewall tries to block online access sometimes. While many games that are made by well-known developers don’t run into firewall issues, it’s not uncommon for games from small developers to have problems based on the code by which they operate or known server issues. For example, Minecraft’s Java Edition is flagged by firewalls because of known security issues with Java code. It’s not the game itself but the code in the game. Other games like Roblox that include small games from independent developers on their servers might run into problems with malicious software.
Let’s walk through how to update your firewall to allow Spotify, Minecraft, and other games or apps onto your computer.

How to allow Minecraft through your firewall. There are a couple of ways that you can update your firewall setting to allow a game like Minecraft through your firewall. The first is the easiest because you’re simply responding to a prompt from your computer. It’s not unusual to get a notification from your security software that the firewall blocks a feature of an app. Take note when the notification pops up because it likely won’t include Minecraft in the name of the program. Rather, it’ll say that it’s blocking Java. If you have admin access, click “Allow access,” and you’ll be set to go.
If you bypassed the original notification because you thought it was for something else, you’ll need to take a few more steps to get into your antivirus software and update your settings. Update your firewall settings by accessing your system’s firewall in the security settings, which can be found in the Settings application. Once you’ve reached Settings, follow these steps:
- Scroll down and click “Update & Security.”
- Click “Windows Security” on the left-hand side of the window.
- Under the “Protection areas” list, click “Firewall & network protection.” This should open a new window.
- Below the main options that have icons, you’ll find a list of options that don’t have accompanying icons. Click “Allow an app through firewall.”
- You’ll see a long list of applications that are allowed and disallowed through your firewall. Select “Private” (for your private network only) for Java, and Minecraft will be allowed past the firewall.
- Click “Allow access” and input your admin password.
“Think of your firewall as “Jeeves”, a steadfast doorman who decides who’s allowed in and who’s not. But sometimes Jeeves oversteps his bounds.”
How to update your firewall to allow Spotify. Updating your firewall to allow Spotify requires a few more steps than for a video game, but you can still make the change and enjoy your music, podcasts, and audiobooks. Start by going into your firewall settings the same as you would for Minecraft, but you’ll want to specifically look for Spotify. Click “Allow access” and input your admin password to complete the process.
An alternate solution to allowing Spotify through your firewall is to change your proxy settings. Take the following steps:
- Open your Spotify settings.
- Click the Proxy type drop-down menu and select “No Proxy.”
- Save your changes and restart Spotify. You’ll likely have to log in again.
Your firewall is an important piece to keeping your computer safe from malware, but it can also be somewhat of a hassle by periodically overstepping. You can always override your firewall to allow apps and games that you’d like to have access to the internet through. Should you override your firewall’s default settings, make sure that you’re being extra careful with servers you join to play games and links you click on in ads.

What Does Firewall Got To Do With Minecraft?
You might be thinking, “What does a firewall have to do with Minecraft?” Well, firewalls are like security guards for your computer. They help protect it from hackers and other bad stuff you don’t want on your computer. But sometimes, they can also block things that you actually want to use – like Minecraft.
When you’re trying to play Minecraft, and there’s something wrong with the connection or it just won’t load properly, it could be because of your firewall is blocking the game. Firewalls work by checking all incoming and outgoing traffic on your computer (like when browsing the web or downloading files) and blocking anything suspicious or unknown.
Since firewalls aren’t familiar with every single program out there, including games like Minecraft, they might think that this traffic is potentially harmful and decide to block it.
Now that we know how important a role the firewall plays in our gaming experience, let’s figure out what needs to be done about it. Allowing Minecraft through the firewall means telling your computer’s security system
“Hey! This specific application is totally cool and safe.” That way, the firewall will stop interrupting your gameplay whenever it suspects some sort of danger.
So what should we do next? The good news is that letting Minecraft past your Firewall isn’t as complicated as it sounds. Once we look into changing some settings in our computers’ firewall settings section up ahead, getting back into our favorite pixelated world will be a breeze.
Firewall Settings
Let’s dive into allowing Minecraft through your Windows 10 firewall so you can have a smooth connection.
You might be having trouble joining servers or friends’ worlds, but don’t worry – we’ve got you covered. We’ll take you through the steps to ensure your computer allows Minecraft to use the internet without interruptions.
First off, let’s head over to your firewall settings:
- Press the “Windows” key and type “firewall” in the search bar.
- Click on “Allow an app or feature through Windows Defender Firewall.”
- This will open up a list of apps and features that are currently allowed (or not) through your computer’s firewall.
Now it’s time to find Minecraft on this list! Scroll down until you see “Minecraft Launcher” or something similar. If it’s already checked under both “Private” and “Public,” then congratulations, you’re all set! However, if they aren’t checked yet, here’s what to do:
- Click on the “Change settings” button near the window’s top right corner.
- Now you should be able to check those boxes next to Minecraft.
- Make sure both “Private” and “Public” are ticked for better connectivity!
Great job! By now, you should have successfully allowed Minecraft through your firewall, which means no more annoying connection issues when trying to join servers or play with friends online.
But sometimes, even after taking these steps, there might still be some problems with connecting properly. That’s why we will explore another way of ensuring a seamless gaming experience: port forwarding.
Also read: Minecraft Full-Screen Problem
Port Forwarding
Port forwarding is like opening a special door in your firewall just for Minecraft so that you and your buddies can play together without any hiccups.
First, open up your router’s settings page by typing its IP address into a web browser on your computer or device connected to the same network as the server.
You’ll need to log in with the username and password (you might want to ask your parents if they set it up). Once logged in, look for something called “Port Forwarding” or “Virtual Servers.” This is where all the magic happens!
Now let’s get down to business. In this magical place called port forwarding settings, create a new rule or virtual server entry specifically for Minecraft.
Type in a name like “Minecraft Server,” then enter the IP address of the machine running the server (usually found under ‘status’ or ‘network information’ within router settings), followed by entering “25565” for both start and end ports – this number never changes unless Mojang decides otherwise.
Set protocol type as TCP/UDP since both are used during gameplay. Save these fantastic adjustments made.
Your super-cool Minecraft world should be accessible now from outside your home network using its public IP address – which can be found easily through searching ‘what’s my IP’ online. It’s always good practice to test everything after making changes, so keep reading our next section about testing connections before celebrating too hard.
Test Connection
Now that you have allowed Minecraft through your firewall and set up port forwarding, it’s time to test if the connection issues are resolved. This is an important step because sometimes problems persist even after making changes. Don’t worry; testing the connection is easy and will help us figure out if we need to do any more troubleshooting.
Launch Minecraft on your computer or device to start testing the connection. Try joining a multiplayer server like you normally would, or ask a friend to join your game if you’re hosting one yourself.
Pay attention to whether the game loads quickly and without error messages. If everything seems smooth and connected well, then congratulations! You’ve successfully fixed the problem by allowing Minecraft through the firewall and setting up port forwarding.
However, if you notice that there are still issues with connecting to servers or having friends join your game, don’t get discouraged. It might mean another issue besides the firewall settings and port forwarding. We’ll need to investigate further to find a solution that works for you.
Before troubleshooting other potential causes of these pesky Minecraft connection issues, double-check all previous steps taken were done correctly.

Troubleshooting
One common reason that might be causing trouble is a slow or unstable internet connection. Make sure you have a strong Wi-Fi signal, or try using an Ethernet cable instead of wireless.
Restarting your modem and router could also help improve the connection speed. If nothing changes after trying these steps, it might be worth checking with your Internet Service Provider (ISP) for any ongoing network issues or maintenance in your area.
Another thing we need to check is if our game files are up-to-date and not corrupted in any way. You can easily repair or re-download missing files by launching the Minecraft launcher on your computer and clicking “Options” next to the play button.
From there, select “Force Update!” This will ensure all necessary files are updated, so everything should run smoothly again!
Don’t lose hope if you’ve gone through all these steps but still can’t connect properly! It’s time to roll up our sleeves and start troubleshooting even further.
Check whether other players are experiencing similar problems – maybe something bigger, like a server outage, is affecting everyone at once? Additionally, consider contacting Mojang Support for assistance; they may have insights on resolving your specific issue.
Conclusion
In conclusion, we can see that firewalls play a significant role in our Minecraft gaming experience. By adjusting the firewall settings and port forwarding, we can solve most connection issues and enjoy playing with friends.

In this article, we are going to setup the Minecraft server and discuss the question – “how to allow minecraft through firewall?” by forwarding traffic through a secure tunnel and as a result bypass a firewall or double NAT problems.
We all love to play Minecraft with friends and create crazy worlds together. To achieve this we should have a Minecraft server, but wait should we buy one in the cloud and spend a 100$ per year for this? We definitely have an old laptop or PC which can serve as great hardware for the Minecraft server. First of all, we are going to install the Minecraft server in our hardware, and then we are going to expose our server to our friends?
Setup Minecraft server
Setting up a multiplayer Minecraft server is quite an easy task. By following https://www.minecraft.net/en-us/download/server link you can find the latest version of the Minecraft server and download it to your computer. Before starting the server you should have Java installed on your computer. Nowadays Java comes with all operating systems by default, however, for Windows, you may be required to play with the PATH environmental variable – It is required to make sure that you can use java from the command line.
To start Minecraft server you should run the following command:
java -Xmx1024M -Xms1024M -jar server.jar nogui
The first run may seem exits with some warnings and errors:
[12:33:18] [main/ERROR]: Failed to load properties from file: server.properties
[12:33:18] [main/WARN]: Failed to load eula.txt
[12:33:18] [main/INFO]: You need to agree to the EULA in order to run the server. Go to eula.txt for more info.
However, it is ok! It justs created default configuration file for a server called “server.properties”, another file for end-user license agreement called “eula.txt” and informs us about accepting the license. To accept the license we should open “eula.txt” file and replace “eula=false” statement in the last row with “eula=true” then save the file and close.
Now is the time to run following command again:
java -Xmx1024M -Xms1024M -jar server.jar nogui
In case if you want to start the server with a user interface you can omit “nogui” argument from the command above. The user interface is not showing much, however, you can see memory usage status, players, logs, and chat.
That’s it! We have a functioning Minecraft server installed, now let’s go to the part where we are going to answer the question of “how to allow Minecraft through firewall?”.
How to allow Minecraft through firewall?
By default, the Minecraft server is listening to 25565 port, however it can be verified or changed in the “server.properties” file (see the row “server-port=25565”). To allow our friends to join we should somehow expose this port to the internet to allow incoming TCP connections. We have many options to achieve this such as:
- 1. Tunneling
- 2. Port forwarding
- 3. VPN
Each of these options has their pros and cons. Here you can find a detailed comparison of different methods for exposing a local server. In this article, we are going to use tunneling for exposing the Minecraft server to the internet, since Tunnel In is aimed to create and manage network tunnels. This method is secure and with our platform it is easy to use and elegant way for exposing any local network service to the internet.
That is all you should do in your computer, the rest you should do from Tunnel In’s web portal i.e. it means after installing an agent all configuration can be done remotely.
Now lets create a tunnel and expose local server to the internet. For that just go to the Tunnels tab and click on “+” button in the bottom right corner. Name the tunnel, select your device, select CUSTOM type for the tunnel, and enter the port number (by default it is 25565). Remove two checkboxes from Security Options (see picture below) and click on the “ADD” button.
The system will create and start the tunnel automatically. In the “Connection properties” column, you can see the URL pointing to your local Minecraft server. By clicking on the URL system will copy it to your clipboard. You can use this URL for connecting to your server from anywhere in the world. Send it to your friends and enjoy playing together!
Now when we know how to allow Minecraft through firewall lets speak a little about how to secure our server.
Tunnel security options
While you can use the Minecraft server with your friends it is time to speak about the security options of the tunnel. In the tunnel creation process, we saw the “Security Options” panel which provides a way to limit the connections to tunnel by IP address, time and connections count.
Here are a short descriptions of each option:
- 1. Connection rate limiting – At most 6 connections are allowed in any 30 seconds window. This is great to stop DDOS attacks on your server
- 2. Initialization time limiting – After starting the tunnel system gives 180 seconds to establish a connection to the tunnel, once that time expires the system will not accept new connections, however, the connections established within the first 180 seconds will keep working.
- 3. Automatically close tunnel when not in use – this is self-explanatory. This option will help you to automatically decrease the attack surface on your server. BTW this is one of the reasons we are against port forwarding.
- 4. Allow Connections From – this option supports 3 different things by now – Allow connections from anywhere, list of IP addresses to allow connection from and the last one is dynamically detecting IP address when you are starting tunnel and allow connection only from your IP address.
