WAN interface is on VLAN 10 and INTERNAL interface is on VLAN 20. If I connect a server behind VLAN 20 on the switch where the firewall is connected everything works fine. The problem is when I connect to another switch that is getting VLAN 20 over a 802.1Q VLAN TRUNK. In this scenario the server cannot be reachable. I think this is related to ARP requests. Any lights on this?

Just to clarify, all server inside VLAN 20 are reachable within the VLAN. Just that firewall traffic  from VLAN 10 to VLAN 20 is not reachable.

We have 6506e at the core, and interVLAN routing is working fine. The problem is implementing FortiGate firewall in transparent mode and terminating the ISP on the router with Ethernet output.

I am not able to route VLANs to public IP through Port 13. What is the best way other than through Network Address Translation (NAT)? My NAT is not working fine with VLAN to Port l3.
