Goto Webmin-Webmin Configuration->Ports and Addresses
set Liston on IP's and ports to specific port e.g. 10010
Logout of webmin and restart it.
To be even more secure you can specifically set webmin to only accept conenctiosn from an exact IP address. Use this if you have static IP and only ever plan to login from one location.
