For starters, you should verify you have the tun/tap driver package installed.
zypper in vtun tunctl
I’d be a bit surprised if you installed any VPN packages already (did you?) where your tun/tap isn’t already installed (it’s pretty basic and common to many types of vpns). The above command installs what may be missing (vtun) and the tool to manage (create/configure/remove) your tun/tap device (tunctl).
Yes i have it installed
about the command you give i get this
*Loading repository data…
Reading installed packages…
‘tunctl’ is already installed.
No update candidate for ‘tunctl-1.5-22.1.2.x86_64’. The highest available version is already installed.
‘vtun’ not found in package names. Trying capabilities.
No provider of ‘vtun’ found.

So it doesnt work. mmm another idea why is looking that particular file, i read something about and they say it is for firewall or something like that i am not really surjust guessing, I am talking about tun0
/sys/devices/virtual/net/tun0: couldn’t determine device driver; ignoring…
I read from other forums the problem could be libgcrypt11 package maybe there is a way to downgrade the packge.
