RouterOS Beginner Basics

hi
i am using mikrotik 493G router-board.(routeros: 4.64.6) for doing some simple tests and i have some simple questions:

as you see in this picture i simply added some IP addresses to router ports and some automatic routes have been generated
/ip address> add interface=ether1 address=192.168.1.1/24
/ip address> add interface=ether2 address=192.168.2.1/24
/ip address> add interface=ether3 address=192.168.3.1/24

i am trying to implement below rules:

  • PC2 and PC3 can not ping each other


  • PC2 and PC3 can communicate with PC1

at the mommet all can ping each other

please provide me with terminal command in router

add action=drop chain=forward in-interface=ether2 out-interface=ether3
add action=drop chain=forward in-interface=ether3 out-interface=ether2
