Good day 
First sorry my English, but I will try to be as simple as possible.
I have a RB750G with two interfaces internal LANs,
network 10.x
network 20.x
And each internal network, has its respective DHCP server, DNS, QoS,
I created two internal interfaces, just to split the traffic between the two networks. Each Mikrotik interface is attached to a respective VLAN (layer 2) with my Switch HP.
The problem I am facing is that being in the 10.x network, I can communicate with other computers on the network 20.x. With the use of Vlans this could not be happening.
It seems that the internal interfaces of Mikrotic, are allowing routing between themselves. Does anyone know how ressolver this?
I thank you for this space and excuse the spelling errors.
