>I have a 3rd party app that listens on a particular port, lets call it port X. Clients are using this app on this port. Now a new client asks if he can rather use it on port Y. Although the app allows me to change the port it listens on I do not know how this might affect existing users (I don't think any of them use a corp. firewall and so did not have to configure anything anyway). Still, it is a concern. I am not a networks expert so have little knowledge but I remember the term "port forwarding" and seem to think it was the ability to forward all inbound traffic coming in on some port to another local port and it would also reverse the outbound traffic in the same way. Does anyone know about this and, if so, what one uses to do this? It is a Windows 2008 R2 server.

Are these different clients utilizing the same instance of the server-based application, or are we talking about different instances of the app running on different servers?

If I'm not mistaken, the port forwarding would be configured on the firewall/router on the server side rather than at the OS level.
