Hello, how can i make the rb450g to work : eth1(gateway) -> eth2, 3, 4 ,5 (lan) without bridge, only in filters. If it is possible. ( Tutorial or something like this. ) .thank you

1 - Put each port into switch mode with one master (eth1?)
2 - Set up individual networks on each interface and use IP routing

What are you trying to achieve?
