When your OpenVPN network is blocked by Deep Packet Inspection, as a Windows user, you can use tor to get it working again. In this article we ll describe steps necessary to port your TCP OpenVPN traffic through Tor-network. This way you will be able to bypass Deep packet inspection and connect to OpenVPN server from Iran, China and other countries where they commonly block ports used for VPN communications.

When openvpn is blocked by DPI we could use Tor to avoid DPI and then use encryption software like the openvpn to access internet.

Problem : When censorship is applied, the Openvpn network is often blocked by DPI.

Solution: We’ve developed OpenVPN with the Tor Browser Bundle to fight back against censorship.

Limitation:

  • only the TCP configs files works over the tor.
  • only work on the desktop (Windows, macOS and Linux).

Send encrypted data over a Tor connection to an exit node. This secures your communications against DPI. By running Tor and OpenVPN Servers on top of tor, you are making yourself a privacy fortress.
