Does blocking 192.168.0.0/16 also block addresses on 192.168.1.0/24?
-
I was looking at some of the examples people have for blocking the RFC1918 addresses. Does blocking 192.168.0.0/16 also block addresses on 192.168.1.0/24? Wouldn't those be two different networks?

@ronpfs I'm not sure how that helps me. Could you provide some more details about what I am looking at?

@shjfliejfasel Input your networks and see if they overlap.

@ronpfs So are you saying that if the IP ranges overlap, then the firewall will block those IP addresses, regardless of what their "Network Address" is (one has a network address of 192.168.1.0 and one has 192.168.0.0)?
[Edit] I did some more reading and realized that subnets can overlap and that is an incorrect design. I thought all subnets were unique and couldn't overlap, that is where my confusion was.
