NAT TO MULTIPLES LANS WITH SAME SUBNET

Dear friends we recently bought a mikrotik router board in order to implement some prtg(Network Monitor) in our infrastructure, however we are getting some inconvenience trying to implement the solution.

We have a prtg computer that need to be connected in the interface 13(mikrotik), in the other hand we have connected some catalyst switches that need to be connected in interface 1, 2,3 …8.(mikrotik) by UTP clable, The problem is that some catalyst switch and servers connected have the same ip addres.
In this case the idea is tray to create an specify nat and route table that identify when the router need to redirect traffic to interface1 or interface2…. Or interface and do a nat depending of the source ip address.
Important, all traffic need to be handle complete insolate by interface depending of IP and the prtg computer need to reach all ips servers or dispositive back to the catalyst swtiches, this mean that we need to nat all ips address.

Please take a look to the attached file, that create an idea how we need to the nat

Thanks in advance.

Um, I would deal with the clash in ip address ranges first.

But what you need to do is look at marking packet from interfaces and routing rules per interface (VRF in routeros talk i think).

nat and route based upon mark and interface based upon

Its a very big pain ..
