firewall block netbios...?

RouterOS General

How to do the following:

Block Windows file sharing, through entering IP (\192.168.101.75\ or similar) or through my network places… the situation wanted is…

computer1 192.168.101.75/24 must have access to the 192.168.1.0/24 network, but the users (hosts) from 192.168.1.0/24 network must NOT have access to the host on 192.168.101.75/24, particulary and only windows file sharing.

currently both computer1 and 192.168.1.0 network have access to each other, and the diagram would be
computer1-router1-router2-network 192.168.1.0/24

The firewall rules should be added on the router1 as some users are also directly connected to router1 (to other interface/network than computer1)..

thank you very much!

firewall - filter - forward - add connection state = new dst-address=192.168.101.75 protocol=tcp dst-port=135-139,445 action=reject
