Hi,
I'd like to connect the Raspberry PI to router A (via Ethernet), and PC to router B (via Ethernet), and send a short message ("turn on GPIO #23) from the PC to the Raspberry PI.
Once the PC and R-PI get each an IP, how do I send a short message over the internet from the PC to the R-PI?
I believe I'd need to do that via Port 80 to avoid any blocking issue due to security - but how do i send a message from PC to R-PI via Port 80?
Thank you.
