I am using XG 450 with version 18.5. We have to control traffic between LAN and DMZ with internet also. We have three subnet running in DMZ. I have created three vlan interfaces with gateways of the subnets as vlan interfaces. Created three different sub zones in DMZ for controlling the vlan subnets. Created a firewall rule with source lan and out bound as sub zones of the DMZ and reserve as the case. I unable to ping the server from my lan. Using any any solves the problem. But cant control the traffic between LAN and DMZ. No nat rule has been created for this purpose.
