Complete Guide to Diablo 3 Port Forwarding Guide

If you want to have the best experience playing Diablo 3 with others online, you should think about setting up Diablo 3 Port Forwarding. This will help you play seamlessly with other players. By adjusting the settings on your router, you can make sure that your internet connection is good when you play games online. This will help to prevent interruptions or being kicked out of the game. You can use the right equipment to fully experience the fun and adventure of Diablo 3 and make your character even stronger.

Blizzard Entertainment created an exciting change with Diablo 3. The server side is where everything like dungeons and monster AI is stored and controlled. Things are taken care of. This game online is very interesting, and port forwarding can help to get rid of any slowness you might experience.

Diablo 3 Performance Boost: How Port Forwarding Can Help

When you play games or browse the internet, your router receives communication requests from outside devices. These requests are then processed, and access is granted to the device making the request.

Port forwarding simplifies the process by granting the device access to internal services of your home network through unique “ports” assigned to manage those requests. The data moves through these ports, shortening the connection routes and allowing for faster data transfer. By using port forwarding, you can significantly improve the speed and efficiency of your network.

This results in a smoother internet experience, but it’s not limited to browsing. Online games, such as Diablo 3, benefit immensely from this. You, the player, are allowed to have lag-free and seamless gameplay during sessions.

Things You Should Know Before Port Forwarding Diablo 3

Port forwarding can be somewhat of a tedious process, and that’s why people tend to avoid it. However, if you are willing to go forward with it and reap the benefits, then you are going to require the following things:

Gaming Device & Router (Static) IP

The IP address of your internet device aka Router and the device that you will be gaming on is necessary. You can find both by following these easy steps for your device:

  • Windows: Go to Command Prompt. Run the ‘ipconfig’ command. Your router’s IP address will be displayed as the ‘Default Gateway’, and the device’s IP address will be displayed as the ‘IPV4 Address’.
  • Mac: Enter System Preferences. Go to Network > Wi-Fi/Ethernet. Click on the ‘Advanced’ button in the bottom right. Navigate to the TCP/IP tab. You will find the router’s IP as ‘Router’ and the device’s IP address as ‘IPV4 Address’.
  • Console: Navigate to the Settings menu of your gaming console, and then Network Settings. The ‘Default Gateway’ will be the router’s IP, and the ‘IPV4 Address’ will be the device’s IP.

Router Login Credentials

The router’s login credentials allow you to access your router’s settings. Once there, you can configure your router the way you want. These login credentials are usually found behind the router, or inside the user’s manual.

Before you begin your search, you could try a generic username-password combination like ‘admin-admin’. If you are unable to locate the required credentials, you should contact your ISP and request assistance.


These ports are the ones your network traffic will be routed to while playing Diablo 3. Ports can either be single numbers or ranges. They also vary concerning the device and application, so look at the chart below to find the correct ports for your device.

Step-By-Step Guide to Diablo 3 Port Forwarding

If you have everything prepared, you may start the port forwarding process. The steps to do so are following:

  • Open any browser.
  • Enter your router’s IP as the URL.
  • Log in and navigate to the port forwarding section. In some instances, it may be labeled as something different like Virtual Servers.
  • Add new rules and enter your device’s IP alongside the relevant port numbers.
  • Once all ports have been added, save the changes.
  • Restart your router to allow the said changes to take effect.

Troubleshooting The Opened Ports

Before you begin enjoying your improved Diablo 3 experience, you must troubleshoot all opened ports. To check whether opened ports are working correctly, follow these steps:

  • From your device’s browser, open the Port Checker Tool.
  • Enter the same ports you entered previously and begin verification.
  • The tool should successfully connect if ports were opened correctly.
  • If the tool does not connect to some ports, then those ports are not working. Thus, the problem needs to be verified and solved first.


Port forwarding is an excellent way of reducing latency in online games. However, there are times when it might not work. You would want a backup plan. Even if it does work, additional help is always welcome, right? That is why we suggest using VPN.

  • VPN provides fast and stable VPN speeds with unlimited bandwidth.
  • Their services are available in more than 91 countries.
  • VPN does not keep activity logs, so your browsing remains anonymous.
  • They also use state-of-the-art AES encryption to ensure your data remains safe.


Why is port forwarding not working?

There are times when port forwarding may be unsuccessful. There may be rule conflict in the presence of too many rules, the firewall could be blocking traffic. Your ISP could have disabled port forwarding on some ports, or you might be behind a CGNAT network.

Do I need to enable port forwarding for Diablo 3?

It is not necessarily required of you to enable port forwarding. It is optional and only exists as a means of improving performance for the game. If you don’t want to enable port forwarding, you could just use VPN.

Can VPNs help with port forwarding?

Some VPNs have a way of enabling port forwarding built into them. VPN only provides port forwarding for routers running their firmware. However, even by itself, VPN can provide network stability to enhance your gaming experience.

Final Verdict

The single-player and multiplayer modes in Diablo 3 are really great. Playing with friends and teaming up for raids and dungeons is really enjoyable. However, frustrating waits can easily ruin the fun. Port forwarding is a good way to make your online games run smoother and reduce delays. We hope you were able to continue your journey after reading this post and successfully moved forward.
