Hi everyone:

I´m triyng to access to a printer witch IP is 10.0.20.2/22 and vLan ID 20 from computers in 10.0.30.0/23 and vLan ID 30.
Can anyone help me to setup that please?

Thank you.

SOLVED: Mikrotik allows communication between vLans by default.
You have to "isolate" vLans if you want to secure them.

The problem was printer´s netmask (manually typed in the device...)

More generally, routeros will route any network to any network unless you have a drop rule in the forwarding chain! If you have no rules in the forwarding chain and the router has internet access on a port then you should add some!

That's right, perfectly explained what I tried to say with "You have to 'isolate' vLans if you want to secure them."

Thank you!!
