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

I can only base advice on the User Manual.
ge3 is configured as LAN, ge4 as DMZ by default. Did you change the zone for latter?

To be able to use firewall policies to the full extent, you'll need to put the LAN interfaces into different zones, as policies are applied whenever traffic crosses zones (not interfaces). For intra-zone traffic you can only set up allow-all or deny-all (not sure about that, the manual is ambiguous at page 209).
I recommend to use two zones like "Students" and "Admin", and put each interface into one of them, then set up policies to define which kind of traffic may be passing. You can set up different rules for the admin network to have full access to the students', while blocking anything but ICMP coming from students network.

Okay cool. I will try to fix that. For now they are in zone "LAN". But both in that zone. Whenever i pick LAN1 or LAN2 zone, the WAN connection seems to not be connected to LAN1 or LAN2.

Are zones just something you configure? Or does it actually does something specific? Or can you create your own zone, with your own rules? And that is kinda how zones work?

For me it seems like zones are doing something to the ports. But i dont have to use them. I can use port 1 as WAN if i like, and port 2 as LAN etc. etc .?

Is this true?Unavngivet.jpg

You can create and names zones as you like. New zones require new firewall rules, though.
Interfaces have a default zone, but you can change that. Interfaces can be member of exactly one zone.
