Schematic
I am trying to access MySQL DB from the MySQL DB client as shown in the above schematic.

The TRB140 is directly connected to the DB host using LAN and I can telnet to IP 192.168.2.212 on port 3306 from the TRB140(SSH session).

The TRB140 is connected to the OpenVPN server on the cloud and I can SSH into TRB140 from other clients like the MySQL DB client on the OpenVPN network.

Now, I want to access the DB from a MySQL DB client (participant of the OpenVPN network with the IP 10.8.0.2). This client can also SSH into TRB140 as shown above.

Port forward settings on TRB140
This doesn't work, I tried Traffic Rules and they seem to offer very similar settings as the port forwarding option but neither works alone or together.
Any help is highly appreciated.
