The problem looks to be your subnet specification. /24 is 256 addresses. So for your 192.168.0.10/24 export, you’re exposing it to 0.10 and the following 255 IPs.
The closest thing to what you want to achieve would be a /29, which would expose it to the given IP and the following 7 IPs.
No, if you mean 192.168.0.0 - 192.168.255.255, that is a /16 192.168.0.0 - 192.168.0.255 is a /24 192.168.0.0 - 192.168.0.7 is a /29
I was a little glib in my initial response. You really don’t want to start your definition in the middle of a subnet.
I would set it up so your first group of /29 would be 192.168.0.0 - 192.168.0.7
Second would be 192.168.0.8 - 192.168.0.15 (192.168.0.8/29)
Third would be 192.168.0.16 - 192.168.0.23 (192.168.0.16/29)
And so on.
