I have two device which can be accessed only using internal network.
To access it externally i have installed nginx in raspberry device and added a redirect within nginx like
location /device1
{
return 301 http://192.168.0.1:80
}
Similarly device2 i have added and now i have used ngrok and exposed the localhost:80 externally.
Problem: If i am in the same network of device1 and device2 i am able to connect it.
If i change my network i am able to access the nginx default page.
Now If i append device1 it says page not found.
Solution Required:
How do i connect device1 and device2 from different network.?
Why is this required say for example i am running a application in amazon i want to connect to my internal device ip and access the data.
You need to use nginx as reverse proxy for that. The very minimal configuration is
location /device1/
{
proxy_pass http://192.168.0.1/;
}
With this configuration request GET /device1/some/other/path will reach your device as GET /some/other/path. If you remove the trailing slash of http://192.168.0.1/ string, same request will reach your device as GET /device1/some/other/path. What you are trying to do commonly called "proxying something under some URI prefix", and depending on what you are proxying under this prefix, there can be various issues.
