This is a bizarre question, but as we are stuck in bizarre times known as COVID-19, I'd have to ask.
The situation is that I have a KRC4 (KSS8.3.33) with KUKAPROXYVAR (KPV) installed, I have a custom program that can send commands to KPV by setting the IP and port number.
The controller is plugged into a wifi router thru the KLI port. The router DHCP is configured for 172.31.0.2 - 172.31.255.254, and the controller is assigned 172.31.1.147. This works perfectly, I can access the controller when connected to that router and send commands to KPV thru port 7000.
Now i'm thinking of doing this over the internet, as some of my students are in quarantine, but I still want them to be able to work with the robot.
Yes I am aware of the risks involved, both physically and device security wise. I'll only connect the router to the internet when needed, the robot speed will be slow, and I'll be monitoring the robot with my hands on the stop button anytime the robot is being controlled. I've also cloned the entire SSD just in case...etc
I've tried port forwarding, opening a port on my router to 172.31.1.147:7000, but when I try to access the controller from another network, it doesn't work. Just wondering if anyone have done anything this bizarre and can give me some pointers.
