Hello! As a complete beginner in home networking I am a bit lost with my problem. Maybe someone can help:

Setup: Internet socket in the wall -> Fritzbox-router -> Linksys router with OpenWRT and a VPN (NordVPN)

I have to Networks I can connect to, the Fritzbox-Network (192.168.178.) and the OpenWRT-Network (192.168.1.). Most PCs/Smartphones are connected to the OpenWRT-Network to be a bit more protected with the VPN. Some are connected to the Fritzbox.

Now two questions:

  • How can I connect those two networks so that I can e.g. ssh from 192.168.178.10 to 192.168.1.30?
  • Who is providing the DNS, when I connect a PiHole to the Fritzbox, set it as DNS-Server and then connect my PC to the other network, which is routing everything to NordVPN? Does NordVPN use its own DNS-Server?

What do I need to learn to understand my own network better?

Well I would create 2 networks in your OpenWRT, Net1 would be tunneled over the VPN and Net2 will break out locally.

On Net1 you basically keep what you have.

Then you assign the NC Server to Net2. You can even create a SSID for this network (call it Guest or whatever) for when somebody needs your WiFi. Or if you want to connect a device you don’t care sending outside the VPN.

Afterwards you can go and turn off the WLAN in your Fritzbox. The telephone will continue working over DECT most likely.

You will probably also need to “expose” the OpenWRT on your Fritzbox. What this does is forward all traffic, unfiltered, to your OpenWRT. You need to do your own research to see if you want to do this, otherwise just forward porta as you need them.

Two networks on the OpenWRT is a really good idea, thank you! With the next free weekend and some duckduckgoing I should be able to implement this.
