OpenVPN with both IPv4 & IPv6
« on: February 15, 2011, 09:48:50 AM »

Hello,

I have setup IPv4 VPN using OpenVPN sometime back on my OpenVZ VPS, and recently brought-in IPv6

from HE.NET.

but I don't seem to be able to serve both IPv4 & IPv6 through my current OpenVPN setup, so I might be

missing something.

Are there any tutorials that can help with this?

My VPS is running Ubuntu jaunty + OpenVPN 2.1_rc11
My Computer (The Client) Windows XP Professional + OpenVPN GUI 1.0.3

Probably the tun driver on Windows doesn't support IPv6?

Is the OpenVPN server running the interface in tap mode?

Windows only supports TAP mode.  I don't know if the windows TAP driver can do ipv6 or not.

Yes,  but the Ubuntu OpenVPN server does maybe not run in tap mode.

I use the OpenVPN source from github (https://github.com/jjo/openvpn-ipv6-legacy21/) and had no issues with IPv6 in relationship with Windows clients.
Well, the Windows clients also use the regular openvpn application from openvpn.net.
As far as I know the official 2.1_rc11 should also have no issues in general with IPv6 to connected clients.

Yeh mine doesn't do IPv6 yet either.  I'm running under gentoo.  I should probably see if the IPv6 capable version is in portage yet.
