Hi,

Im trying to run openvpn within docker, but I’m seeing the following error trying to connect the tun device.

VPNs are not possible, please see [https://circleci.com/blog/vpns-and-why-they-don-t-work/](https://circleci.com/blog/vpns-and-why-they-don-t-work/) for details.

Per this post is a possible workaround though

> Hi DoryZI You can’t create a tun/tap driver on lxc, Circleci made a blog post [1] explaining this. Nevertheless I create a proxy socks [2] to redirect all traffic to my internal network and solved this vpn problem.
