Flash remoting connection

hi everyone
can someone please help me on this?

i’ m working on an application that uses flash mx 2004 pro with flash remoting for .net, the problem is that as long as i work on my localhost server it works fine, but as soon as i put it working with other server it keeps returning me the message , “could not load type”

i have a dynamic ip at home, where i’m trying to work with this, anda i’, using the no-ip services to get around this, but i can’t seem to get it working .
