Kerberos is a computer network security protocol that authenticates service requests between two or more trusted hosts. Kerberos helps to ensure that data exchanged between two hosts is secure and cannot be accessed by unauthorized individuals. If you are looking to port forward Kerberos, this guide can help you.
Port forwarding is used to allow remote access to a computer or device that is behind a firewall. When port forwarding is properly configured, the firewall will know to allow incoming traffic on the specified port and forward it to the correct computer or device on the network.
Requirements to Port Forward Kerberos
Just before you begin with the process of port forwarding, make sure you have the following things:
- Downloaded and installed the Kerberos server.
- The IP address of your router.
- IP address of your device.
TCP and UDP ports of Kerberos are mentioned in the section below.
Step-by-step guide on how to port forward Kerberos

- Navigate to the port forwarding section of your router.
- Click on Port Forwarding.

- Put the TCP and UDP ports of the Kerberos server in the boxes in your router. The default Kerberos port number is 464. And then click the apply button.
- And you’re done. Restart your router to let the changes take effect.
- Once your changes take effect, now you can host a Kerberos server and let your friends connect to it as well. To let them connect to it, you need to provide them the hostname you are using, along with the port number. For example, ‘hostname.domain.com:25565’.
