Set up Firewall as Switch

Kean

Since im always bored i tried to set up a USG40W as a Switch and i cant get it to work.
I disabled Policy Control since i only want it to be a Switch and not a Firewall.
My DHCP Server has an IP of 192.168.69.1(255.255.255.0) and it will give the WAN Port on the USG a IP(192.168.69.17) but it will not give an IP to any Clients connected to P2. I have set up a DHCP Relay on LAN1 with the 192.168.69.1 IP but the Clients do not get a IP.
The LAN1 interface is configured with 192.168.69.2 and DHCP Relay. LAN1 is set to all possible Ports.
If i give the Client a static IP and try to ping 192.168.69.17 it works but i cant ping 192.168.69.1.

Are there any extra settings i have to set?

You will not be able change the WAN1 but if you do this the four ports will run as a switch but you will not be able to firewall or you could bridge LAN1,LAN2, OPT and DMZ if you don't change port role.
