I have a VPN server, I build it my own and I am using it with 1 more person, so I am sure that the IP isn't flagged as a VPN server, and I am curious how netflix and other services are detecting that I am going through a VPN. It's the TTL of the packet? It's the source port of my server that leads to that conclusion? Is there something else that I am missing?
Kind regards and thanks for the help.
