Scenario:

Because USG20(W) and USG Flex 50(W) don't have LAN3 zone by default. I the user wants to add a LAN3 zone to manage the LAN clients more flexibly how to deploy it?

Answer:

If the customer would like to use P3 for the LAN3 zone with IP 192.168.66.1 and DHCP server, please refer to the below steps:

Configuration > Object > Zone > To add a new zone named LAN3.

Configuration > Interface > Port > To adjust guest to P3.

Configuration > Interface > Ethernet > To rename guest to lan3.

And set its IP address to 192.168.66.1/255.255.255.0.

Set DHCP server-related settings.

Configuration > Security Policy > To add a policy to allow LAN3 outgoing traffic can access the internet.

Then the user can get a DHCP IP from the LAN3 and access the internet.
