A double VPN setup routes your traffic through two VPN servers in different countries, making your IPTV origin nearly impossible to trace. On Linux, you can achieve this with OpenVPN + WireGuard. First VPN runs on host; second runs in a VM or Docker. Ensure Xtream UI only listens to localhost (127.0.0.1) or internal IP via nginx.conf. This setup protects your real IP even if one VPN fails. Monitor latency though—it adds 50-100ms typically.
