A customer of mine, recently asked me to look into a problem with his SNOM OpenVPN enabled
handsets, they were working – just had an annoying “VPN:Error” message at the bottom of the
screen, it seems to be that the fix is to declare the device as a tun0, but make sure that
the device type is tap (yes yes I know tap / bridging is not exactly ideal but the customer
wanted it this way).

Anyhow all fixed now and the config is posted below :-


# It's a client config

# The device is called tun0
dev tun0
# However it's a tap device - just happens to be called tun0
