Hello,
I have 2 LAN MFP printers and i want them to be seen in two different networks. The main problem is that i do not wish computers from one network to ping or see computers in the other network. Lets say printers have ip 192.168.1.20 and 192.168.1.21 could i connect them in both networks that use ip of 192.168.1.40->54 and 192.168.1.80->104. I understand that this could be made with port isolation in SwOS. how can it be done in RouterOS though…?
Thanks.
Dimitris.
Firewall rules and clever address masking ?
Roughly speaking,
If you can divide both LANs as 1-127 and 128-254 a /25 subnet mask should help for the filters ?
Or something along those lines 
Well you are barking up the wrong tree.
All those users are in the same LAN or subnet so they can all see each other. (same network)
What you want is two subnets or two vlans for example.
192.168.1.1/24 address and
192.168.10.1/24 address etc.
This is normal and easily accomplished via firewall rules.
