    # MC Port Tunnel SSH Service

    Usecase -> not able to port forward in your network.

    **Assumptions:**
    12345 is the mc server's port that its opening on the remote server (25565).
    User `mc` is the user on the minecraft server.
    User `minecraft` is the user on the cloud SSH server.

    If you have fail2ban installed, make sure to add the following to `/etc/fail2ban/jail.local`:
    ```
    [DEFAULT]
    ignoreip = (public ip address of the private network its running on; the one you're tunneling out of)
    ```
