I want to ssh to my Raspberry pi that will be on a different network from my home network. ON my home network router, I set up port forwarding: Set the WAN and LAN start and end ports to 22, set the protocol to TCP. The WAN Host IP address (start & end) set to 192.168.x.x (it is going to be static so i set the same start/end address), and the LAN host IP address to my static IP inside my home network. Now, from inside my home network, how do I ssh to the rpi? Is it >>> ssh username@public_ip_address?

  • As far as I understand you want to connect to your RasPi on the internet from a device on your local network. Does the RasPi have a public ip address? Can you ping it from the local device? Please address me with @Ingo, otherwise I won't see your reply. – Ingo Jun 29 at 11:38

You must use 0.0.0.0 for translate an unknown IP address (because it can be dynamic). Redirect all TCP input traffic from all IP addr port 22 to your host to destination 192.168.0.2 (from my example) and port 22 (change this port for prevent mass scanning)

enter image description here Where 92.x.x.x.x is PUBLIC IP and 192.168.0.2 is PRIVATE IP.

then use :

ssh -p 22 pi@92.x.x.x.x

You must test this configuration from a device behind the N.A.T router. But you can access to your local SSH server with:

ssh -p 22 pi@192.168.0.2

from a device that is on the same network as your 192.168.X.X/X network.

Note: example for IPv4 only.
