You can probably fix this.
If you choose full route will route all your traffic through the tunnel you chose.
Smart route will ONLY route the traffic you specify on the Routing > Domain config and Routing > IP config.
There you specify also which tunnel to use. The tunnel you select should be present on the Tunnel list and should have an IP AND the "Switch IP" blue button enabled (meaning it is available to be used as tunnel).
If you choose full route you will see that it works.
