Router behind a router - how to connect two networks?
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?
You're viewing a single thread.
My first question is why do you have/need two routers?
My suggestion would be get rid of one or the other and that should solve all the questions you are asking.
Edit: A router is a device that is placed at the edge of your network and controls traffic between inside your network and the internet. If you need more wired connection ports than either router has your setup up should be:
Internet > Router > network switch
I will simplify my network now and connect everything to OpenWRT and use the Fritzbox only as modem.
Yeah this feels like a classic XY problem.
