This will give you an overview and understanding of how you can connect an Adder product running a VNC server to your network and enable remote access. From an outsiders point of view, it appears as though the router is delivering the service.Īs the configuration of a router varies between different makes and models, providing the port forwarding configuration for your specific router and/or firewall is beyond the scope of this page and support, please consult your system administrator. This is done by assigning a specific port number to the external routers IP address and forwarding it to an internal private IP address and port number of a network device on the private LAN. Port forwarding allows external network devices to communicate with a network device that is within an organisations network, also known as a private LAN (Local Area Network). All Adder VNC based products use port 5900 by default, however, this is customisable. A list of well-known port numbers can be found on Wikipedia. The most famous port number is 80, which is normally associated with a web server for delivering web pages such as this.

Software/Firmware on the network device binds exclusively to one or more of these ports for communication to provide a service. This router will have a unique public facing IP address which by definition is accessible by anyone on the internet.Ī port number is a number from 0 to 65535 that is linked to the IP address of a network device. Typically most organisations have a single network router connected to the internet for access.
