(OpenVPN plugin)
ii openvpn 2.1.3-2ubuntu3
virtual private network daemon
The effect is that all traffic gets routed via the VPN, which is not
desired unless configured that way. Without a NAT/routing rule on the
server side, Internet access on the client is broken.
The offending behaviour is documented in the log:
May 26 12:49:00 thinkpad NetworkManager[1148]: <info> Policy set 'myVPN'
(tun0) as default for IPv4 routing and DNS.
