Requirements

1. OpenVPN Connent client software
2. .ovpn file

Expected Behavior

When connected to the OpenVPN client, it will proxy requests to Google only, while using direct requests for other websites or networks.

Solution

Edit the .ovpn file and add the following section, replace the IP range routes as needed.

route-nopull
route 172.217.0.0 255.255.0.0
route 173.194.0.0 255.255.0.0
route 216.58.0.0 255.255.0.0

Complete .ovpn file content would be as follows:

client
dev tun
proto tcp
remote <your_VPN_server_IP_address> <your_VPN_port>
resolv-retry infinite
nobind
persist-key
persist-tun
remote-cert-tls server
auth SHA512
cipher AES-256-CBC
ignore-unknown-option block-outside-dns
verb 3

route-nopull
route 172.217.0.0 255.255.0.0
route 173.194.0.0 255.255.0.0
route 216.58.0.0 255.255.0.0
