Streaming services like Netflix and Hulu are often forced by copyright holders to block VPN services and only make content viewable from specific regions
With OVPN you can circumvent these blocks by activating the Enable streaming services option in the desktop client. With this option enabled, traffic towards streaming services will be rerouted to VPN servers optimized for streaming. All other traffic will still use the normal VPN server. A technical explanation on how this works is available on the blog.
