Assign NAT to IP block

I have a 532 the wan port is dhcp
the LAN 1 and LAN 2 are both seperate networks 192.168.17.0 GW .1 and 172.16.16.0 GW .1

How do you make sure that only one LAN is serviced by a particular NAT confuration. I only seem to have trafic on one indicating that on one of the NAT setup is functioning for both sub nets. I do not want to the 2 LAN net works to see each other by default although I will need to set up some secure access for the techs.

You can specify ‘src-address=192.168.17.0/24’, if you want that dedicated subnet is processed over specified NAT rule.
