==VLAN to VLAN communication with one firewall zone==
==VLAN to VLAN communication with one firewall zone==
Once VLANs are created - they lay under one firewall zone, here is a Topology of the network and the zone which covers all 3 of VLANs:

Initially, when we create VLAN interfaces, all VLANs are able to communicate with each other, for example pinging from lan to lan2:

==VLAN to VLAN communication with inter-zone forwarding==

In order to get more control over VLANs, an '''inter-zone''' forwarding functionality should be used. To start with, we will need to create new firewall zones: LAN1, LAN2 and LAN3. To add new zones, navigate to '''Network -> Firewall -> General Settings'''. In the Zones section, press ADD button to add a new zone.
In order to get more control over VLANs, an '''inter-zone''' forwarding functionality should be used. Here is a network topology with firewall zones and an explanation.

'''Note''': We set up Input and Output zone settings as Accept, this allows traffic to leave and reach this zone. Forward: Reject acts as a default policy - we modify this one via Inter-zone forwarding section.
'''Note''': By setting the Input and Output zones to '''Accept''' traffic is allowed to enter and leave the zone. '''Forward: Reject''' blocks communication between zones - this is a default policy. '''Inter-zone forwarding''' section can be used to modify the default behavior of the Forward zone and allow communication between zones.

Using these examples as a base, you can allow / reject VLAN to VLAN communication between different VLANs according to your needs.
