I just installed my zentyal box and running it for about a week, suddenly today openvpn cannot be started. In zentyal log: 2013/05/31 09:21:11 DEBUG> Server.pm:464 EBox::OpenVPN::Server::localAddress - VPN server mcvpnserver1 couldn't be configured, no IP address found for interface eth0
What could be wrong? btw, eth0 is PPPOE and the IP address is static.
