Adding a OpenWrt/Pi between 4G router & Smart TV?

As far as I can tell, the TV is able to connect to the internet as expected. However, when I enable the OpenVPN service, the Pi is protected (no entries in the traceroute) but the Pi is not? - All the hops from the traceroute command are listed.

Any help would be appreciated.

However, the device connected to eth1 is not using the OpenVPN tunnel (as shown by
