Do you have to use port 25565 for Minecraft?
The short answer is no – using the default port 25565 is not required for running a Minecraft server. The port number can be easily changed by editing the server.properties configuration file. While 25565 is standard convention, there are good reasons you may want to use alternatives:
Why Change the Default Port?
Here are some of the common scenarios where changing the standard port makes sense:
Bypassing gaming blocks – Schools and some network admins block 25565 to prevent access during work hours. Using an obscure port can stealthily bypass these restrictions.
Avoiding port conflicts – Though rare, another application may already be using port 25565 on your hosting machine. Changing the port prevents conflicts.
Running multiple servers – Hosting more than one Minecraft server requires each to have a unique port (e.g. 25566, 25567).
Extra security – Obscurity provides some protection against external port scans searching specifically for 25565.
| Reason | Details |
|---|---|
| Bypass Blocks | Change port to sneak past gaming blocks at school/work |
| Avoid Conflicts | Fix clashes with other apps on port 25565 |
| Multiple Servers | Allow hosting many servers on one network |
| Added Security | Reduce attack surface from blind port scans |
Changing the Port Number
Adjusting the port only takes a few minutes by editing server.properties:
- Stop server
- Open server.properties file
- Edit "server-port" value
- Save changes
- Restart server!
For example, changing it from standard 25565 to 25566:
server-port=25566 Players will need to specify new port when connecting. Otherwise, it should work transparently.
Additional Considerations
Also remember to:
- Forward the new port in your router (if hosting externally)
- Permit access in firewall software
Handling those network configuration changes allows everything to communicate properly based on your customized port selection.
Conclusion
While port 25565 is standard convention for Minecraft, feel free to use alternatives to work around restrictions, gain security, or resolve conflicts on your network. The port number is flexible!
