Getting past router?

Hi all,

Suppose I have a program, and the program
wants to talk to a server at some IP address,
but that server, which is waiting for a connection
on some port, is behind a wireless router.
How can that work? Does a router normally
just pass such a request on to all machines
connected to it?

Thanks.

Well, your question is really to vague to answer
properly. You need to be more specific about the
setup and what you are trying to do.

But guessing I would say, it cannot, and no. But
without more info as to exactly what you are doing,
that is not really a good answer.

That is not a problem. Router works on network layer and if you send a
connection request (I assume that you use TCP) then you needn't have to
care about the router.

The router has to be configured to do so. It's called port forwarding,
although although I think my router calls it virtual hosts.
