Spreading range of IPs on another valid ip valid

Good morning everyone!
I am with the following situation I Telemar link 50 connected to a mega mikrotik Ether1 201.18.xx.x/30
ether2 200.189.xxx.x/24 200.189.xxx.x/24
must create a routing for my clients who are providers a schema like the one I receive from the operator example client1 ip wan lan 200.179.xxx.x/30 pool 200.189.xxx.xx/28 in this case the client would receive the other side as well: eth0 200.189.xx.2/30 gw 200.189.xx.1 eth1 200.189.xxx.1/28 this is your range of IPs valid, I know this is possible in Mikrotik but I’m not hitting the routing rules if someone can help me I will be eternally grateful.
Thank you all!
