How to check what zone a subnet belongs to?

Is there anyway to check what zone a subnet belongs in if there are multiple zones on the firewall?

Preferably through the GUI?

Yes, you can check the IP subnets and interfaces of the zone very quickly in web UI.

Just follow as per screenshot steps.

Thanks for the response, I should have given more detail. If for example I am making a rule using new objects (hosts, networks, etc.) that I have just created, what is the best way to determine what zone I should select for them in the rule?

Do I just check if the IP address of the object belongs in any of the ranges of each zone on the Interfaces tab?

Hello,

Yeah its one of those things you have to understand your network to determine which zone and network the host lives in.

Hope that makes sense.

Supposing you don't know that, for whatever reason, and you just can access the firewall, I'd say:

Network > Virtual Router > More runtime stats > Routing Table, find the route and get the interface type.number for that specific destination
Network > Interfaces > Type > Number, and get the assigned zone for the interface you got at the previous step

Of course, knowledge of your network, as said by others, is always a good and healthy thing to have, when managing a firewall.
