I recently bought a Cisco RV130W router and plan to use it as a secondary router in a cascaded router setup. I want to do this so I can isolate my own devices (NAS, printer, PC, Laptop) and prevent them from being accesible by anyone on the primary network. Also I'd like to use static IPs for my devices.
My (secondary) routers WAN-port is plugged into the primary (internet-facing) routers LAN-port via a switch. The primary routers WAN-port is where the internet comes from. It is a FRITZ!Box 7430, a very common brand in Germany.
I wasn't expecting everything to work right out of the box, but I honestly didn't expect this much trouble either. Various tutorials made this seem rather easy. The router itself DOES have internet access and was able to pull the newest firmware version from the Cisco site as well as traceroute Google with the built in feature on the web interface. All devices on my network are able to talk to each other (e.g. I can print with my PC), but for some reason I'm not able to reach the internet from any of my devices.
My question should be obvious: how can I access the internet from the devices connected to the secondary router?
I already did a couple hours of Google searches yesterday, but nothing could really help me. So far I have only attempted the following:
- set mode from "gateway" to "router" (which disables NAT)
- activated RIP
Admittedly, I've tried nothing and I'm all out of ideas.
I suspect that either the routing or something related to IPv6 might be off, but to me the routing table looks fine at first glance. Then again I've never dealt with anything like this before and this is literally my first experience with setting up a router this way. I think it's best to just post the table here:

Some background info/context: I live in a fraternity with ten other people. Everyone is connected to the internet through a single (primary) router. The situation is quite messy, since this poor router has to handle WiFi for approximately 20-40 devices at any given time (we get a lot of house guests). WiFi is unusably slow and unstable. But worse than that: the combination of static IPs and DHCP means I'm not able to run my NAS without daily address conflicts. Also I fear people might eventually figure out how to print on my network printer.
