    # Assumption
    We assume that a VPN connection is already setup and a `ppp0` interface is up and running.

    # Routing modifications
    Run following commands as `root` user:
    ```shell
    cd /etc/iproute2
    cp rt_tables rt_tables.orig

    echo "1 vpn" >> /etc/iproute2/rt_tables

    ip route add default dev ppp0 table vpn

    ip rule add to 44.205.64.0/24 table vpn #Docker
    ip rule add to 34.205.13.0/24 table vpn # Docker
    ip rule add to 3.216.34.0/24 table vpn # Docker
    ip rule add to 138.197.224.240 table vpn # dist.libuv.org
    ```

    Top 3 IP ranges of the above examples are for `Docker` to pull images through VPN connection. `Docker Hub` is hosted on AWS therefore these IPs might change frequently.

    - Please note that these changes are not persistent and will be lost upon system reboot.
