Block traffic between subnets

Hi!

I would like to block all traffic between my subnets. I have 5 different subnets and they are not supose to talk to each other.
It seems that even if i add rules for this, some traffic is still allowed.

I know that UTM creates its own rules "behind" the webGUI. Could this be the problem?
It feels like i dont really have control over the firewall, some thing are allowed even if i dont have any rules for it.

Any sugestions on how to proceed?

Nothing is allowed between them.

They are only to access WAN.

Hello,

Are you using web filtering? If so, than you will still be able to access web resources (port 80, 443) between subnets unless you specifically deny this access in the web filter.

Can you give an example of which traffic is still allowed? I guessed it might have been web filtering, but if you can be specific on what you've found that comes through, than we might be able to pinpoint where to look.
