Following up to my entry about circumventing geoblocking (https://nextlevel-blog.de/circumventing-amazon-geoblocking-the-tech-way/), I’ve written a small python program solving my Netflix blocking problem.
I realized that Netflix is not working as they rigorously ban the use of VPNs or proxies. Hence, it does work when using my home server as gateway/router but not when I additionaly enable the VPN.
First, I tried to enable or disable the VPN when I see the corresponding DNS queries for either amazon or netflix services. However, it turned out that my TV communicates with each other service regardless of what I am currently using. Therefore it is not possible to identify the desired state.
To ease the trouble at least a bit, I wrote a small webserver which allows me to make the switch with the click on a bookmark.
The following code snippet shows a default setup for a Flask server in python. It listens on the defined IP address and port.
#!/usr/bin/env python3 from flask import Flask import os app = Flask(__name__) if __name__ == '__main__': app.run(host="192.168.42.19", port=5000)
Handling the VPN
To handle the VPN switching I just remove or add the ip rules to forward the traffic either to my wireguard table or using the default one.
A very hacky check routine identifies the current routing state.
def enableVPNRoute(): print("enable VPN") os.system("ip rule add iif enp3s0 lookup 51820") os.system("ip rule flush") pass def disableVPNRoute(): print("disable VPN") os.system("ip rule del iif enp3s0 lookup 51820") pass def isVPNOn(): ir = os.popen("ip rule").read() return "iif" in ir
Establishing the Routes
Finally, Flask introduces the
app.route directives which I now use to enable the VPN if the webserver is called as
http://192.168.42.19:5000/amazon or disabled as
@app.route('/amazon') def amazon(): if not isVPNOn(): enableVPNRoute() return "Turned VPN on. Enjoy Amazon :-)" @app.route('/netflix') def netflix(): if isVPNOn(): disableVPNRoute() return "Turned VPN off. Enjoy Netflix :-)"
Enjoy your next movies and shows 😉
