Hey, could I get some help running the client on my Raspberry Pi I have my server on a VPS with public IP, buy my Raspberry Pi is at home and my ISP doesn't provide a public IP, I'm behind a CGNAT I tried the install script that I get from the access key, but it doesn't seem to be working. I can't ping any other device. Do I have to set it up as an external device? How do I do that on Ubuntu on the Pi, none of the guides I've tried are working. The wg interface is up, but can't ping or communicate
