i registered a domain in no-ip.com but hfs doesn't allow me to use it without the port 
what you mean "without using the port" ?
tell us what is working for you, and what does not.
consider HFS has nothing to do with no-ip working: the embedded feature is just for updating, you can use no-ip without HFS to have any knowledge of that.
so, if no-ip is working for you or not, it should have very little with hfs itself. anyway, provide more info and we may help you.
