Re: [Openvpn-users] tun device on 2.6?

In my particular case, I compiled it into the kernel, rather than being a module.
Hence, it should work without a modprobe. It is the same in 2.4.24, and it works fine.

I did add mktun to the config file on that side of the tunnel, and will try it later, when I have a chance to reboot onto 2.6.
