The sad part about living in Iran from a technology perspective is you are often blocked from both sides. Often you have to circumvent the government's aggressive internal firewall and other times you will have to hide your IP from the service providers.

Using a VPN doesn't prevent the Iranian authorities from detecting that you are using a VPN. It isn't a secure or safe alternative in Iran, particularly with the noisy way it is usually thrown together.
Oh boy, I remember the days you had to be a proper engineer to understand and set up VPNs. Like adblocking making this stuff popular just makes it less effective for people in-the-know.
