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

Hello,

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         188.166.64.1    0.0.0.0         UG    0      0        0 eth0
10.18.0.0       *               255.255.0.0     U     0      0        0 eth0
188.166.64.0    *               255.255.192.0   U     0      0        0 eth0
192.168.10.1    192.168.10.5    255.255.255.255 UGH   0      0        0 tun0
192.168.10.5    *               255.255.255.255 UH    0      0        0 tun0
192.168.200.0   192.168.10.5    255.255.255.0   UG    0      0        0 tun0
