I've been asked to help set up a server with an external IP address so that users in another location can access it. I'm not entirely sure how to go about this. I've been given the external IP address that their Internet provider supplied. Should I install another switch before the internal network switch in order to have the server on the "outside". I've not done much router configuration and am not sure if there is a way to route these users to this server if it is behind their current router. Since it would have a different address would this even be possible? Any advice would be greatly appreciated.
