Re: Traffic between vlans applying security policies ¿possible?
[ Edited ]
I think we can achieve your requirement by using irb interfaces.
Create multiple units under irb for your respective vlans and associate them with security zone - TRUST. If you would like to make a PC in VLAN-10 communicate with a PC in VLAN-40, you need to configure Intra-zone policy. i.e. from-zone TRUST to-zone TRUST policy.
