Cable Modem -> Interface 2 -> interface 3

Hi,

I’m very new to Mikrotik and I wish some help to start.

I wanna put Mikrotik to work in my network, and I wanna ask if my idea is correct:

Cable Modem (as bridge) → Mikrotik interface 2 receive the internet connection and send it to → (interface 3) and when someone connects to (interface 3), it set up an IP using dhcp on the client computer.

Is my idea correct ? Does someone know where can I start ?

This might be a good place to start.
