How to secure http access to your dreambox

If you want to restrict the http access to your dmbox, which is already on default port 80 ((( in an enterprise environment anyone can search the IP and can try to see))) , you can just change the port number to anyother like 780 or 670 by going through setup->expert setup ->communication. After changing this you can browse your dbox by typing the address in IE like this: http://192.1x8.x.x:780 whatever port you use except some specific ports like 12000. pls dont use 12000 as its restricted for cccam protocol.
