Hi network experts,<br />
<br />
I just need to know how can I communicate via a client-server application with a machine(server side of the application) that is behind a router. I have the external IP of the machine but it only work when we set the machine as the default DMZ server. <br />
<br />
My network knowledge is very limited and I'm having an hard time to figure out how can I achieve this. Can it be done via a tunnel or with the route command under DOS? Wath is the most common solution expert use to resolve this kind of problem? I just need a little track to get a good idea.<br />
<br />
Any comment will be very appreciated, thanks in advance.<br />

How to access workstation behind a router with external IP

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
