How to configure CCR-1016-12G?

Hi,

is there someone who help me to configure CCR1016-12G?

I would like to have the this configuration:

Eth1 - DHCP 192.168.10.0/24
Eth2 - DHCP 192.168.20.0/24
.
.
.
Eth9 - DHCP 192.168.90.0/24
Eth10 - DHCP 172.16.0.0/16
Eth11 - not used now
Eth12 - Static IP from ISP - WAN

To each ethernet port will be connected switch with computers.
These computers can see themselves without any restrictions.

Computers on different ethernet ports can’t see themselves, but they must have connection with Eth12 - WAN Internet

How could I do configuration for this requirements?

Untagged VLAN, or something else?

Thank you in advance for your help.
