When you connect with NoMachine from an external device, set the external IP address + the external port in the connection set-up. Port-forwarding is configured on the side that you want to connect to. This is called 'port forwarding' or 'port mapping'. To allow NoMachine traffic to get from outside into your computer at home or office, it's necessary to map an external port to the internal port 4000. Outside the private network, only the external (called also 'public') IP address assigned to the router is visible. You will need to configure port forwarding on your home-based router to access your computer. So, for example, your computer is at home and you want to access it while you are away.

Internal IPs and ports are not accessible from outside. To connect from computerB to computerA, set: To connect with NoMachine from computerA to -> computerB, set in the NoMachine connection: To accept connections from another device, the NoMachine service (nxd) on that computer listens on the internal port 4000 (this is a TCP port).įor example: computerA and computerB are in the same network at home or office. How to enable automatic port forwarding in NoMachine Troubleshooting for most common cases requiring manual configuration of the routerĤ.1.

How to configure the router manually through its administrative interfaceģ.

So, we need to distinguish two cases: (i) when connecting by NoMachine from the same network and (ii) when connecting from a different network like over the Internet. In most cases, the computer is behind a NAT (Network Address Translation) router which translates the internal IP addresses of computers in the local private network to a single IP address, accessible from outside that private network. Įvery computer in a private network like that of your home or office is identified by an internal or private IP address. If you have NoMachine v.8 installed, please consult. This article refers to NoMachine v.7 installations, or earlier.
