That looks correct. To troubleshoot, capture the packets in the Mikrotik. Tools > Packet Sniffer. Set interface to ether5, save capture to a file on the Mikrotik.
Then Ping the remote network from your PC. Stop the packet sniffer, copy the file to your PC and open it with Wireshark.
A route doesn’t change dest IP in a packet, only the dest mac address.
So you should see a ping going into the Mikrotik with dest mac address of the Mikrotik. Then you should see the ping leaving ether5 with the dest mac address of the 192.168.0.210 device.
This test will tell you if fault is with your Mikrotik or the 192.168.0.210 device.
