Digital Router Question:

When trying to communicate with systems on the inside of a secured network, it can be very difficult to do so from the outside- and with good reason. Therefore, the use of a port forwarding table within the router itself or other connection management device, can allow for specific traffic to be automatically forwarded on to a particular destination. For example, if you had a web server running on your network and you wanted access to be granted to it from the outside, you would setup port forwarding to port 80 on the server in question. This would mean that anyone putting in your IP address in a web browser would be connected up to the server's website immediately. Please note, this is usually not recommended to allow access to a server from the outside directly into your network.
