Question:
How do I configure vlan to vlan communication on firewall?
Answer:
Once vlan interfaces are created, they can communicate with each other because of the default implicit allow rule. You can add extra security policy rule (Deny, Source and Destination) to block traffic between vlan interfaces.
If you just allow VLAN interface to access the Internet but prevent it from accessing other vlan interfaces, follow the guide in this article.
