Hi
I recently set up a raspberry pi at my sisters house that vpn's back to my network. Its running debian linux, which I also run at home.
After setup, I wanted to verify that regular internet traffic was going out locally rather than through the vpn, so I ran dig myip.opendns.com @resolver1.opendns.com
I got the usual half page of text except the ip address field was blank. I have since confirmed through other means that the request is going out locally..
When I run that command locally at home, I get the expected response with ip address.
We live about 30 miles apart and use the same isp (comcast xfinity) both computers are running the same version of dig. So why?
I have 2 hypotheses:
1: I run my own router and modem while she runs the comcast suplied one. Maybe her hardware is filtering?
2: She lives near a tech giant while I live in the sticks. Maybe the isp router she connects to is filtering trying to make it harder because the concentration of techies working around their usage rules?
Other Ideas?
