Sorry, but there are no such things like "IP ports". IP is a network layer that hasn't the port concept, which is supported in TCP and in UDP. The fact that you talk about "TCP/IP" later does not help to clarify the matter - simply because the protocol stack is usually referred to as "TCP/IP", but UDP is part of the stack as well.

Why bother about this distinction? Simply because using TCP or UDP could modify dramatically your mileage. You don't say how the intermediate machine is going to take the data, for one thing. Or which sub-connector will be the leader of the main connection, to say another.

The whole mechanism is also quite obscure. You say that "local software connects to that port, processes the data into a database". But later you tlak about having a second client "receiving the same data and the first". There's a model ambiguity here. In the first case the model is more like a pull, in which the client enters and asks for some particular data inside the database. In the second we have something more similar to a push, in which any client is presented the very same data at every session.

The latter case if of course by far the simplest. You only have to connect, download the data, then wait for any connection in other ports. OTOH, the former case is full of pitfalls, because you're basically asking a way to correctly interleave the requests coming from two clients over the same connection, which depends on the particular application.

Don't fool yourself.
