This article explains how to create a Guest VLAN in the TZ firewall, for guest users to access Internet only. Guest users will not be able to access any other Local network.
This release includes significant user interface changes and many new features that are different from the SonicOS 6.5 and earlier firmware. The below resolution is for customers using SonicOS 7.X firmware.
Create a zone for guest VLAN.
 NOTE: Do not enable any of the auto-generate rules for guest VLAN, that way we can add the specific firewall rule only for internet access. If communication is needed to any other network we need to create access rules accordingly for them.
Create a Virtual interface.

Enable DHCP scope for newly configured VLAN Interface.

Configure Guest VLAN zone to WAN zone access rule.
