What steps will reproduce the problem?
1. Connect to an OpenVPN server that provides v6 service in the v4 tunnel
2. The Chrome OS OpenVPN connection does not tunnel its IPv6 traffic (other clients do)

What is the expected result?
IPv6 traffic is properly tunneled.

What happens instead of that?
IPv6 traffic goes out the non-VPN IPv6 network.

Please provide any additional information below. Attach a screenshot if
possible.

Is IPv6 not supported under Chrome OS's OpenVPN? The version of OpenVPN, 2.3.2, supports v6 traffic in the tunnel.
