VPN Support - OpenVPN

[wjbeckett]

Would love to have VPN support so all torrent traffic was routed via the VPN (OpenVPN for example) however the web interface on port 80 was still accessible via the local interface (non-VPN).

+1 for that

+1 for OpenVPN support

I thought I'd try installing openvpn in the downloaded container and if it worked, I'd add it to the Dockerfile.

I ran a bash in the docker container:

$ sudo docker exec -it 93210504de5c bash

Then, in the docker container, tried to install openvpn but no luck:

root@93210504de5c:~# apt-get install openvpn

Also tried apt-get install openvpn --fix-missing but that failed too.

Update 1
Looks like openvpn was installed despite all those errors.

I had to add --cap-add=NET_ADMIN --device=/dev/net/tun when running the container to add /dev/net/tun which is needed by openvpn.

Then in the command line:
$ openvpn --config your_vpn_config.ovpn

And it works like a charm 👍 It just needs to be automated and streamlined in the Dockerfile.

@rhazegh Six weeks on, are you using the above on a regular basis? Any issues?

@ribmo I only did some experiments but did not use this for real.

I think if one wants to use VPN for a torrent client, all network connections should be blocked if the VPN is dropped. I am not sure if these settings provide this requirement.
