Question: 

I create a vlan interface with base port lan2 and assign it to a customized zone as follows. Why can't my device on this vlan interface ping gateway IP?

Answer: 

If you have configured a device on VLAN interface with lan2 as the base port with its own zone but the device cannot ping or connect to gateway IPs, it is likely due to a missing security policy rule.

To resolve this issue, ensure that you add an extra security policy rule to allow traffic from the VLAN zone to the ZyWALL.This will permit your VLAN interfaces to communicate with the ZyWALL, enabling ping and connectivity to gateway IPs.
