How to enable PPTP on the home WiFi

I started using Orange this month, and I am facing an issue—I can't connect to my company's VPN at home.

My company requires us to use PPTP (Point-to-Point Tunneling Protocol) to access the VPN.

I have called Orange's customer service a few times, but they always tell me that my VPN settings are incorrect.

However, I was able to connect to the VPN at my friend's house, so I know that the VPN settings are correct.

Do you know how to enable VPN access using PPTP at home?
