i mean when u add a new client and this client have a Wi Fi device exp just like access point TP-link 743 u connect the device and u have configured it and every thing is oky , after that what the rule u should add in Mikrotik to can acess this device
Mikrotik default Lan IP is 10.10.50.2 and the device 192.168.2.35 which rules u have to add to make connection between that Different range of IP
If you add natting device into your network and you want to see what is hidden behind it, you need to set the dst nat rules on it to open and redirect required ports to the devices behind or do the routing instead natting if your tplink supports it.
