Host to Host Connection not happening via Mikrotik Router

[paddyvgc]

You dont need nat or static routes !!! Just add in firewall filter 2 rules:
/ip fi fi
add chain=forward src-address=192.168.12.0/24 dst-address=192.168.110.0/24 action=accept
add chain=forward src-address=192.168.110.0/24 dst-address=192.168.12.0/2 action=accept

As you mentioned , I removed the masquerade nat policy and added the above chain rules.
Still the Host 1 to Host2 connection is nt working.

Pls help
