VPN for Iran
Using the internet in Iran
If you are in Iran and looking for reaching sites and apps that are filtered, without the connection being detected, the obstacle is specific and so is the answer.
What is actually blocking you
Deep packet inspection identifies and drops most VPN protocols, and the blocking gets heavier around events.
What gets through it
Protocol mimicry makes the tunnel look like ordinary HTTPS traffic, and bridge mode routes through a second hop when a direct connection is refused.
