Hi all

Im working on a school. For now we used 2 routers with its own WAN to seperate student and admin network.

I want to get rid of 1 router, to use the new advanced router for both networks.

Its a Zyxel Zywall 310.

I managed to make 1 WAN, and 2 LAN (see image)
1 WAN to 2 LAN
It works fine because i got seperate switches and cables for each network. So its not a vlan and i guees its not important to create a vlan?
Thats what im asking for.
Is this setup valid? Can the 2 networks connect to each other? They may not be able to.
I know they can ping eachother, but a part from that, the networks most be completely seperated. Are they?

Is there anything to take into consideration, before deploying this pretty simple setup?

Best regards
