Help with dual network setup

I'm thinking about using OpenWRT and would like a little guidance before jumping in. I'd like to achieve a few things with my home network and I'm hoping I can achieve most of it with something like OpenWRT.

I'd like to have:

  • Two networks
  • One has access to the other but not visa versa
  • Both have access to the internet
  • Both support ethernet and Wifi connections
  • One has bandwidth throttled. (nice to have)

Basically I want one network for personal devices (phones, laptops) and another for anything IoT or otherwise that doesn't need access to personal devices.

It looks quite similar to guest WLAN:


Similar yes. But the piece missing there is that some devices need to connect to that secondary network via ethernet.

The most canonical way to achieve this is by splitting VLANs:

Then you create a new IoT network as a bridge interface based on the IoT WLAN and the new VLAN.
The same way as the LAN network works for the main WLAN.


Thanks for the links! I have this setup. I've tested some with a raspberry pi on the GUEST interface via a VLAN. I can ping/ssh to it from a device on the LAN interface, but the raspberry pi can only ping devices on the GUEST interface.

The real test will be when I move all the devices to the new networks. Fingers crossed.
