My net consists of one router mikrotik (routeros) and many switches (“not clever”).
Is it possible to change direction packets through router ? I want to close permission for some devices (printers.. etc).
I found one way to do it. Make additional subnet and move all devices to the new subnet.
But maybe i’m wrong ?
How I said before, all computers and printers connected through switches.
and (! important ! in one local net) i.e. if i ping from computer 192.168.1.100 to printer with IP 192.168.1.101, packets doesn’t reach
router. And i can’t make firewall rules.
OK - so you are talking about traffic within the LAN environment and not external traffic. You need some way to differentiate the devices which you want to apply the rules to. VLANs would do this very well so check if any of your switches support VLANs. Overlaying a second subnet on the same physical network would also work but gives you none of the other advantages of VLANs. Grouping controlled devices on a particular switch could work (along with proxy-arp) but probably isn’t practical for you and would be a messy solution anyway.
