Traffic won't forward between interfaces

I learn to configure mikrotik recently. and i find i missunderstood something about ethernet switching in RB750 RouterOS.

I configure my mikrotik RB750 ethernet interfaces like this:

lan0 192.168.10.1/24 master-port=none
lan1 192.168.11.1/24 master-port=none
lan2 192.168.12.1/24 master-port=none
lan3 192.168.13.1/24 master-port=none
lan4 192.168.14.1/24 master-port=none

The route of each interfaces shown in /ip route print as Dynamic Active and Connected.

The problem is i can’t ping each others if each interfaces using “master-port=none”, but It can if I use “master-port=lan0”, and lan1 thru lan4 marked as SLAVE, but… I got icmp redirect-Host, which meant all the network is on the same interfaces.

I hope somebody could en-light me here

Need more details to help in this case.

What are your firewall filter rules? I’m guessing that you have a specific filter rule that is dropping everything not explicitly accepted further up in the forward chain.
