You are almost certainly hitting this TAP driver issue: https://github.com/OpenVPN/tap-windows6/issues/3
There are two possible solutions: - Downgrade the TAP driver to the old version (the one provided with tinc) - Upgrade the TAP driver to the fixed version which is included in the latest OpenVPN installers at http://openvpn.net/index.php/download/community-downloads.html Note that I did not have time to test the new driver version so I don't know if it will work reliably (or even if it really fixes the issue). If in doubt, you should downgrade.
