How to make routing between two interfaces?

Question

Mikrotik

Good evening dear! Help, please, I can’t solve the problem for 2 days already.
There are two routers:
1. Cisco, address 192.168.0.210, network 192.168.0.0/24, landlord’s network
2. Mikrotik, it has 2 interfaces, tenant’s network:
2.1) local, address 192.168.43.254, network 192.168.43.0/24;
2.2) external, it has an operating mode as a normal switch, address 192.168.0.138, network
192.168.0.0/24 And from the network 192.168.0.0/24, the network 192.168.43.0/24 does not see and does not ping.
How to make network 192.168.43.0/24 visible from network 192.168.0.0/24? It is necessary to register routes in Mikrotik or in a tsiska?
I apologize in advance if this is a dumb question. Please understand and forgive. :-)
Thanks for the replies!

Firewall rules need to be disabled. You don’t need to do anything else, everything will work on its own, because. it is a router, the main function of a router is to route traffic between networks.
