Configuring CRS behind WiFi Router while using all LAN ports

RouterOS Beginner Basics
1

Hi, new RouterOS user here.

I recently got a CRS328 and my plan is to place it behind my existing router.
This router will handle all wireless connections and provide DHCP leases to all network devices.
Meanwhile, all wired devices will be connected to CRS.

Additionally, the router has 4 LAN ports, each on a different subnet. It also supports creation of multiple networks which combines the wireless and wired devices connected on each of the LAN ports. With the introduction of the CRS, I want to extend each of the LAN ports of the router so that they can accommodate more wired devices.

The closest setup that I can imagine is to create 4 bridges and configure them to connect to one of the LAN ports.
However, bridge seem to require NAT which hides all the devices under it.

Or, another way to think about it: having one dumb switch on each of the LAN ports of the router. I could have gone that route, but that is besides the point at the moment. :slight_smile:

Attached is a simple diagram of what I have in mind. If you have any suggestions, or if you think my planned setup does not make sense, please inform.

Thank you!

One bridge, use vlans.
Vlans are the bread and butter of switches so best get use to them.
THe Router will have a different style of vlan setup so enjoy you get to learn both of them.

For the router this is a good starting point.

Rough methodology provided…


For the switch, read the applicable reference…

Note you will only need one physical port to the switch from the router!
