I have a standard network and wanted to make a more secure one so I bought a second router and set it up as a separate network daisy chained so it can get internet.
I managed to make the setup, with one network having addresses from 192.168.1.60 - 192.168.1.253 (router was 192.168.1.254. The second router had addresses from 192.168.0.1 - 192.168.0.50 (router was 192.168.0.1). Subnet mask is class C 255.255.255.0.
However I found with this setup, I could still ping devices from the x.x.0.1 network to the x.x.1.1 network. Does this represent a security issue as I thought the two networks are separate and so should not be able to ping each other?
