I can connect to an OpenVPN server from Windows without any problems. But when I try to connect from Ubuntu 12.04 (start OpenVPN) I receive the following: OpenVPN needs a gateway parameter for a --route option and no default was specified by either --route-gateway or --ifconfig options SERVER IP: 161.53.X.X internal network: 10.0.0.0 / 8 What I need to do ? client configuration: client dev tap proto udp remote 161.53.X.X 1194 resolv-retry infinite nobind ca ca.crt cert client.crt key client.key ns-cert-type server comp-lzo verb 3 server conf: local 161.53.X.X port 1194 proto udp dev tap dev-node OpenVPN ca ca.crt cert server.crt key server.key # This file should be kept secret dh dh1024.pem # DHCP leases addresses to clients server-bridge # Push routes to the client to allow it # to reach other private subnets behind # the server.
