Hi
I’m trying to configure my network has this diagram but I‘m not achieving the correct config. I’m a newbie on mikrotiks. (although I‘ve achieved how to do it with only the router mikrotik, my problem is computers that arrive from the second mikrotik/switch)
Can anyone give me some lights on this?

So the first box is a router or a modem? It doesnt look like your getting a true WANIP but a LANIP from the first box (heading to the cloud router switch).
It also looks like you want to use the hex solely as a switch correct??
