How to setup and route traffic over Open VPN client on Ubuntu 16?


I need help with configuring OpenVPN as client on Ubuntu 16. I installed OpenVPN and successfully started connection but I don’t know how to correctly route traffic to go through that connection.

This is my route table:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         UG    0      0        0 eth0       *          U     0      0        0 eth0    *        U     0      0        0 eth0 UGH   0      0        0 tun0    *      UH    0      0        0 tun0   UG    0      0        0 tun0
