UDP for permanent link between server and client? |

Hi
I need to write an application to link two hosts located on different networks. The server reads data periodically from a database; when a certain piece of data appears in the DB, it should send a signal to a client located in another network.
To avoid having clients open up their firewall and map the port to the host inside, I'd rather let the clients connect out to the server.
Question is: Can the clients maintain a link to the server if using UDP, or must I use TCP for this project? Based on the little I know, I think that UDP won't do, as there's actually no connection between client and server.
Thank you
