Mikrotik router has 2 sections - Input and Forward. Input section is for incoming traffic, and Forward - traffic that passes through the router. If you need to manage access strip networks, then this is usually done in the forward section. How to configure the firewall so that traffic works correctly - rules and security
Allow forwarding between the LANs. If you have firewall rules that drop forwarding, add rules like:
/ip firewall filter
add chain=forward src-address=192.168.1.0/24 dst-address=192.168.10.0/24 action=accept
add chain=forward src-address=192.168.10.0/24 dst-address=192.168.1.0/24 action=accept
