Open a port in the firewall

Almost all companies protect their network by a firewall. This firewall is only open for a very few things or ports like HTTP (Web-server) and SMTP (e-mail).

The Remote Server application is a TCP/IP based server accepting a configurable TCP/IP port number (default port number is 2000) .

The IT-department could open the current port number (e.g. 2000) for IP traffic directed directly to the Remote Server therby making it reachable from the Internet. This is possible because the Firewall will convert the port number to an internal IP address on the Intranet (NAT). In addition it might be possible to configure the firewall so that only acceptable IP-adresses (callers) can use the specific port.

Note that service providers (callers) will probably need to ask their IT-department to open for the port to be opened for communication out of their network.

This solution gives a high level of certainty that no misuse of the company network can be done. An extra global IP address is NOT needed.

Note that if you have multiple Remote PC's, each will need a specific port.

Note that there is no protection against users that have a Remote client application.
