Greetings Experts

I often notice attacks on our FreeRADIUS server. To stop these attacks, i
am thinking to change the default authentication port from 1812 to
something different.

1.) Is it correct thing to do ?
2.) Would it even help ? Stop or reduce fake auth attempts ?
3.) How do we modify the default port to set different port for FreeRADIUS?

Thanks / Regards
