client VPN connected on Asus RT-AC66U_B1 but traffic does not pass through

Hi,

I was able to use my tunnelbear account to setup the openvpn client, it connects ok, bit non of the device's traffix is going through that tunnel.

https://whatismyipaddress.com/ is always showing my ISP IP.

Anybody know how to automatically route all traffic via VPN ?

Thanks

J
