Verify firewall/routing configuration

Hi,

running a small home network with various VLans:

  • Edge Router Lite
  • 1 x Zyxel Switch
  • Raspberry pi for DNS

Using the firewall on the router, I was able to segregate the different networks and it “seems” to work; but I want to be sure. Are there any software tools out there that allows me to probe the network in a systematic way. Naive picture: Laptop with 2 NICs, plugin into two different ports on the switch and run various tests against the neworks; e.g. does it route, can it reach other endpoint, DNS available … etc.

Does something like this exist, or how is it done in the enterprise?

– Thx
