I am trying to set up an NFS share for devices in the blue network (WiFi). The NFS server is located in the green network. The picture shows my network setup.
I currently have the problem that I cannot ping the devices in the blue network (repeater = 192.168.150.2 and laptop = 192.168.150.110) from the server with the IP address 192.168.200.10. From the PC with the IP 192.168.200.21 I can ping the repeater and the laptop. The server works in headless mode, so I establish a connection from the PC (192.168.200.21) via SSH for configuration and ping. This should not be a problem.
The Green Network should reach the Blue Network without any problems! I have not blocked the server in my firewall rules!
Be careful with pings and Windoze machines. The Windoze firewall generally blocks pings from outside its own subnet, so it is best to temporarily drop the firewall while testing, or set up a an exception in the firewall for the green subnet.
