Hello Andrew!

For people to help you out you'll have to provide some more information.
Eg. Are you having error messages? Couuld you post them? What have you tried that isn't working? :-)

If you don't do this I think the down-vote trolls will start attacking your question.

"Connect to client" is neither possible nor impossible. This is just the oxymoron. Client connects to server, and the server and client send/receive messages in both directions, or on one direction, does not matter. Hence, the server needs to have IP known to the client, accessible to this client. And client needs the port number. Client's IP address is totally irrelevant.

Server doesn't ask client that "Please come and connect with me". It is the client that connects to the server. Therefore Client must have the IP of the server, which you have already. And the server must have IP known to the client and client must have the port number.

And to address your problem, if you want that your server can connect to the client, then your client should have such mechanism (i.e Proxy) that it can behave like server and the server behaves like it is a client.

The proxy of the client-server needs to be there on both the side in order to achieve something like whatever you're trying to say.
