You can't do this.  You can't have a 192.168/16 subnet and a
192.168.2/24 subnet in the same enterprise.  It won't work.  Change the
192.168/16 subnet to 192.168.1/24.  Otherwise your subnets overlap.

"well paid" maybe.

Because then your network is correctly configured.

Don't. :)

I think this all goes back to your incorrect subnetting.
