Question: 

How can I configure VLAN interface to access the Internet but prevent it from accessing other VLANs?

Answer: 

  • testvlan can access Internet
  • testvlan cannot access other internal subnets

To achieve this configuration for VLAN interface, follow these steps. You don't need to create extra security policy rules.

1. On Nebula, go to Configure > Firewall > Interface > LAN interface.

2. Select the VLAN interface and turn on the option labeled "Guest". For further details, you can refer to this FAQ.
