do you have a firewall policy between wan-1 and lan-1 for the communication between subnets to be allowed ?

hello,

 

you will have noticed that you cannot set the same VLAN ID on 2 different ports of the FGT. The FGT is running as a router/firewall so subnets must be unique. The plan you've got calls for a VLAN switch.

I'm not saying the FGT couldn't act as a VLAN switch as well but IMHO the easiest way to complete this setup is to use VLAN ID 3013 for the WAN link. It really doesn't matter which ID as long as it is different.
