Routing with VPN doesn't work, I wonder why?

Hi,

I'm establishing a VPN connection, but it doesn't seem to work like I thought. Here's the resulting routing table ant the traceroute output:

I tried to specify in my OVPN file route-metric 0 but no luck, all packets are still not using my VPN at all. What should I change to make my VPN interface tun0 to be default and the only interface for all TCP/IP communications on my machine?

Go to the web page at https://phoenixnap.com/kb/openvpn-centos and scroll down to step 5.
I just wrote an article on setting this up for the LCFS series. This is not an easy setup, whether it is CentOS or Ubuntu. No matter your distro, this should help. The problem is you need to MASQUERADE the firewall.
