Perhaps you have inadvertently enabled it through the QuickSet settings?
That aside, you can disable the L2TP server if you’re not using it:
/interface l2tp-server server set enabled=no
You should also blacklist the IPs which seem to have gained access to your subnet as well as change username and password for good measure
