tun device in devfs.conf?

[Steve Kargl]

Hi,

I've been told that I must use a VPN from my home system
to connect to work.  I've installed openvpn.  As a normal
user, who is a member of wheel and operator groups, I execute

% openvpn config.txt

openvpn ends with
 
Wed Aug  8 13:46:29 2018 Cannot allocate TUN/TAP dev dynamically
Wed Aug  8 13:46:29 2018 Exiting due to fatal error

Is there a devfs rule that I can add to /etc/devfs.conf
to allow the normal user to create a tun device?
