Sorry if this is in the wrong place.I don't really know anything about server-related things, but I'm really curious about this.

On my mac I figured out how to make a simple web page viewable via the local ip address or computer name on the LAN, and also how to hook it up with a free hostname from dyndns.com.

So the dyndns hostname points to something, how can I access it directly?

Typing in the global ip address (of the router) doesn't work, but if it did, how would it know which computer to point to?

There must be some way of directly accessing what dyndns hostname points to by typing in some number, right?

Sorry I don't really understand how it works.
