Welcome to Tek-Tips.

Your question is awfully vague making it difficult to respond. Perhaps you should have a look here for starters:

As far as what you need to do with your gateway, it sounds like you are referring to port forwarding to your server that is in a private LAN. How you do this will depend on what you are using for a gateway.

If the above doesn't answer your question, perhaps you could elaborate on what it is that you are trying to do?
